Description

FIELD OF THE INVENTION

[0001] The present disclosure relates to an alloy containing aluminium and magnesium, a method for the manufacture of said alloy, a method for the manufacture of a product comprising said alloy, a product comprising said alloy, and in particular to the use of said alloy in an extrusion or other wrought manufacturing process.BACKGROUND

[0002] Extrusion processes are used as forming process for a variety of aluminium products, such as rods, wires, tubes, hollow profiles, solid profiles, and irregularly shaped prismatic profiles.

[0003] Such products desirably have high elongation combined with high strength. Such properties provide for excellent energy uptake capacity of the aluminium products. Therefore, such aluminium products find application in automotive industry, e.g., in the manufacture of mechanically stable parts of a car to provide increased crash safety for the passengers. Further applications of extruded aluminium products may be in aircraft engineering, shipbuilding, train construction, and the construction sector.

[0004] A crucial aspect in the manufacturing of aluminium products by means of extrusion processes is the aluminium alloy. Such alloy must have a coarse grain structure to provide for sufficient deformation characteristics, i.e. good formability, which are essential for successful extrusion. It is understood that the microstructure of an aluminium alloy is refined during forming by an extrusion process. This results in a refined microstructure of the aluminium product and hence increased strength and elongation properties.

[0005] Therefore, it is understood that aluminium alloys used in casting applications or the like are not suitable for application in extrusion processes: Such alloys are generally designed to provide high strength after casting. However, this means that high forces are required during extrusion which exceed the limits imposed by the available extrusion presses and plants.

[0006] Another important parameter in forming of aluminium alloys by extrusion is the extrusion temperature, the level of which is limited by the respective alloy composition, in particular by its resistance to heat impact. Since local heating of the alloy can occur during forming, melting can occur, especially in the region of the die, which impairs the mechanical properties of the final extruded product.

[0007] In conclusion, the design possibilities in extrusion are mainly influenced and limited by the type of alloy, the available process forces and the direction of extrusion. The advantages of extrusion are in particular the possibilities of producing profiles even in complex shapes. The high degree of forming that can be achieved in one process step and the low tooling costs make extrusion particularly interesting for the production of relatively small batches.

[0008] In the prior art, a variety of metals and alloys are described to be suitable for the manufacture of products by means of extrusion or wrought processes, including aluminium and aluminium alloys which are manufactured into heat sink profiles and construction profiles. Frequently, copper and copper alloys or stainless steel is used to produce seamless tubes.

[0009] The quality of the extruded part depends not only on the machine settings and the tool design (geometry) but also to a large extent on the alloy system selected. Predominantly, AlMn(Cu) alloys from the 2000 or 5000 series alloys according to the International Alloy Designation System and AlMgSi alloy systems from the 6000 series alloys according to the International Alloy Designation System are widely used for extruded products. The chemical composition and microstructure of an aluminium alloy is a decisive parameter in the manufacturing of aluminium products by means of extrusion processes for the resulting product properties.

[0010] Usually, the required mechanical properties, especially a high strength in terms of yield strength Rm and tensile strength Rp0.2 are achieved by adding copper and / or zinc to the alloys. In addition, these alloys are subjected to a heat treatment in order to achieve an improvement of the mechanical properties through the hardening effects. In this process, metastable phases are formed to counteract dislocation movements when force is applied. Alternatively, Al—Mn alloys (3000 series alloys according to the International Alloy Designation System) may also be used.SUMMARY OF THE DISCLOSURE

[0059] m) of from 0 to 1% by mass of nickel (Ni);

[0060] n) of from 0 to 0.5% by mass of cobalt (Co);

[0061] wherein the aluminium alloy further comprises inevitable impurities;

[0062] with the balance being aluminium (Al);each amount in relation to the total mass of the alloy composition, and wherein all compounds of the alloy add up to a total of 100% by mass.

[0064] In a preferred embodiment of the first aspect, the aluminium alloy is suitable for extrusion and / or wrought applications.

[0065] In another preferred embodiment, the inevitable impurities are present in an amount of less than 0.15% by mass, or in an amount of less than 0.1% by mass, or in an amount of less than 0.05% by mass. This relates to the total amount of impurities as present in the alloy.

If more than one impurity is present, each impurity is termed as “individual impurity”. The amount of each individual impurity is preferably less than the respective given amount, and the sum of the amounts of each individual impurity results in the total amount of impurities.

[0067] One of these individual impurities may be thallium (Ta), resulting in an amount of Ta of less than 0.05% by mass, or in an amount of less than 0.01% by mass, or in an amount of less than 0.001% by mass, or in an amount of less than 0.0001% by mass.

[0068] Another one of these individual impurities may be gallium (Ga), resulting in an amount of Ga of less than 0.05% by mass, or in an amount of less than 0.01% by mass, or in an amount of less than 0.001% by mass, or in an amount of less than 0.0001% by mass.

[0069] Still another one of these individual impurities may be indium (In), resulting in an amount of In of less than 0.05% by mass, or in an amount of less than 0.01% by mass, or in an amount of less than 0.001% by mass, or in an amount of less than 0.0001% by mass.

[0070] Other examples of individual impurities include cerium (Ce), hafnium (Hf), lanthanum (La), niobium (Nb), molybdenum (Mo), yttrium (Y), or phosphor (P).

[0071] As one of the essential elements, the aluminium alloy according to the first aspect of the present disclosure contains magnesium (Mg) as a main ingredient in an amount of from 6 to 12% by mass.

[0072] In a preferred embodiment of the first aspect, Mg is present in an amount of from 6.5 to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 7 to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 7. to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 8 to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 8 to 11.5% by mass.

[0073] In another preferred embodiment of the first aspect, Mg is present in an amount of from 6 to 10% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 6.5 to 9.5% by mass.

[0074] In another preferred embodiment of the first aspect, Mg is present in an amount of from 8 to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 9 to 12% by mass. In another preferred embodiment of the first aspect, Mg is present in an amount of from 9.5 to 12% by mass.

In another preferred embodiment of the first aspect, Mg is present in an amount of from 11 to 11.5% by mass.

[0075] It is understood that Mg is added to provide the strength and elongation to the resultant aluminium alloy product through solid solution strengthening after extrusion. If Mg is present in an amount of less than 6% by weight, the yield strength and elongation of the aluminium alloy products is reduced. On the other hand, when the Mg content exceeds 12% by mass, the hot workability of the alloy billet or slab is rapidly lowered. This feature in turn, makes it substantially difficult to manufacture the aluminium alloy products, in particular by extrusion or other means of wrought administrations.

[0076] Another essential element in the composition of the aluminium alloy according to the first aspect of the present disclosure is titanium (Ti), present in an amount of from 0.01 to 0.4% by mass in relation to the total mass of the aluminium alloy composition. In another preferred embodiment, Ti is present in an amount of from 0.015 to 0.4% by mass. In another preferred embodiment, Ti is present in an amount of from 0.02 to 0.4% by mass.

In a further preferred embodiment, Ti is present in an amount of 0.1% by mass or less. In a further preferred embodiment, Ti is present in an amount of 0.08% by mass or less.

[0079] In another embodiment, Ti is present in an amount of 0.01% by mass or more. In a preferred embodiment, Ti is present in an amount of 0.015% by mass or more. In another preferred embodiment, Ti is present in an amount of 0.02% by mass or more.

[0080] The aluminium alloy according to the first aspect of the present disclosure contains manganese (Mn) at an amount of 2.5% by mass or less. In a preferred embodiment, Mn is present in an amount 1.5% by mass or less. In a further preferred embodiment, Mn is present in an amount of 1% by mass or less.

In a further preferred embodiment, Mn is present in an amount of 0.0005% by mass or more.

[0081] Also, the aluminium alloy according to the first aspect of the present disclosure contains iron (Fe) at an amount of 0.15% by mass or less. In a preferred embodiment, Fe is present in an amount 0.1% by mass or less. In a further preferred embodiment, Fe is present in an amount of 0.09% by mass or less. In a further preferred embodiment, Fe is present in an amount of 0.08% by mass or less. In a further preferred embodiment, Fe is present in an amount of 0.01% by mass or more. In a further preferred embodiment, Fe is present in an amount of 0.05% by mass or more.

[0082] Another element in the aluminium alloy according to the first aspect of the present disclosure is beryllium (Be), present in an amount of from 0.002 to 0.2% by mass in relation to the total mass of the aluminium alloy composition. In a preferred embodiment, Be is present in an amount of from 0.002 to 0.15% by mass. In a preferred embodiment, Be is present in an amount of from 0.003 to 0.1% by mass. In a further preferred embodiment, Be is present in an amount of from 0.004 to 0.05% by mass. In a further preferred embodiment, Be is present in an amount of from 0.005 to 0.02% by mass. In a further preferred embodiment, Be is present in an amount of from 0.002% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.003% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.004% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.005% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.01% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.015% by mass or more. In a further preferred embodiment, Be is present in an amount of from 0.15% by mass or less. In a further preferred embodiment, Be is present in an amount of from 0.1% by mass or less. In a further preferred embodiment, Be is present in an amount of from 0.05% by mass or less. In a further preferred embodiment, Be is present in an amount of from 0.02% by mass or less.

[0083] It is understood that Be is added to prevent oxidation of the molten metal at the time of melting and casting of the alloy. Be also prevents loss of Mg and superficial change of colour which usually results from oxidation of the slab during melting, extrusion and / or heat treatment. When the Be content is less than 0.002% by mass, Be is unable to effective prevent oxidation of the alloy composition. On the other hand, a Be content of more than 0.2% by mass results in toxicity which substantially impairs the manufacturing process.

[0084] In a preferred embodiment of the aluminium alloy according to the first aspect of the present disclosure, boron (B) is present in an amount of from 0.001 to 0.1% by mass. In a further preferred embodiment, B is present in an amount of from 0.002 to 0.08% by mass. In a further preferred embodiment, B is present in an amount of from 0.002 to 0.06% by mass. In a further preferred embodiment, B is present in an amount of from 0.002 to 0.04% by mass. In a further preferred embodiment, B is present in an amount of from 0.003 to 0.02% by mass. In a further preferred embodiment, B is present in an amount of from 0.003 to 0.016% by mass. In a further preferred embodiment, B is present in an amount of 0.002% by mass or more. In a further preferred embodiment, B is present in an amount of 0.0025% by mass or more. In a further preferred embodiment, B is present in an amount of 0.003% by mass or more. In a further preferred embodiment, B is present in an amount of 0.08% by mass or less. In a further preferred embodiment, B is present in an amount of 0.06% by mass or less. In a further preferred embodiment, B is present in an amount of 0.04% by mass or less. In a further preferred embodiment, B is present in an amount of 0.02% by mass or less. In a further preferred embodiment, B is present in an amount of 0.016% by mass or less.

[0085] In a preferred embodiment of the present disclosure, Ti and B are added to the aluminium alloy melt together, further preferably in bars containing Ti and B in a ration of Ti:B of about 5:1, about 3:1 or about 1,6:1,4, such as TiBloy®. However, the ration of Ti and B in the final alloy may differ from the ratio of Ti and B when added to the melt. Without being bound to said theory, it is assumed that some of the B is removed when removing the dross from the melt. Said dross is removed as it contains agglomerated impurities which are not desired in the final alloy. It is furthermore assumed that B is enriched in said dross, in particular in relation to Ti, due to the low specific weight of B. As such, it is preferred that the ration of Ti:B in the final alloy is in the range of from 3:1 to 10:1, preferably 5:1 to 10:1.

[0086] Ti and B form TiB2 in the molten alloy. Hence, TiB2 acts as nucleating agent during solidification of the molten aluminium alloy and hence refines the alloy. Thus, both strength and ductility are increased.

[0087] Another element in the aluminium alloy according to the first aspect of the present disclosure is silicon (Si), present in an amount of from 0 to 1% by mass in relation to the total mass of the aluminium alloy composition.

In a further preferred embodiment, Si is present in an amount of 0.3% by mass or less. In a further preferred embodiment, Si is present in an amount of 0.15% by mass or less. In a further preferred embodiment, Si is present in an amount of 0.1% by mass or less. In another preferred embodiment, Si is present in an amount of 0.001% by mass or more. In a further preferred embodiment, Si is present in an amount of 0.005% by mass or more.

[0088] It is understood that Si is added to the aluminium alloys to enhance the strength of the aluminium alloy by solid solution strengthening. Furthermore, Si binds excess Mg thus preventing the precipitation of coarse particles of Mg. Upon crystallization, Si and Mg form Mg2Si intermetallic compounds, which increases the strength through precipitation hardening. On the other hand, elongation / ductility is reduced. Therefore, Si may only be added to alloys having a high elongation, such as 50% or more, to further improve its strength. In other words, Si is added to alloy having an elongation of 50% or more.

[0089] Another element in the aluminium alloy according to the first aspect of the present disclosure is copper (Cu), present in an amount of from 0 to 0.06% by mass in relation to the total mass of the aluminium alloy composition.

In a further preferred embodiment, Cu is present in an amount of 0.005% by mass or less. In another preferred embodiment, Cu is present in an amount of 0.001% by mass or more. In a further preferred embodiment, Cu is present in an amount of 0.004% by mass or more.

[0090] It is understood that Cu might only be added in an amount of up to 0.06% by mass. If Cu is present in an amount of more than 0.06% by mass, the aluminium alloy is susceptible to corrosion.

[0091] Another element in the aluminium alloy according to the first aspect of the present disclosure is zinc (Zn), present in an amount of from 0 to 5% by mass in relation to the total mass of the aluminium alloy composition. In a preferred embodiment, Zn is present in an amount of 2.5% by mass or less. In a further preferred embodiment, Zn is present in an amount of 1% by mass or less.

In a further preferred embodiment, Zn is present in an amount of 0.05% by mass or less.

[0092] It is understood that Zn is added to the aluminium alloys to enhance the strength of the aluminium alloy by solid solution strengthening. Furthermore, Zn binds excess Mg forming MgZn2 thus preventing the precipitation of coarse particles of Mg.

[0093] Another element in the aluminium alloy according to the first aspect of the present disclosure is chromium (Cr), present in an amount of from 0 to 1% by mass in relation to the total mass of the aluminium alloy composition.

In a further preferred embodiment, Cr is present in an amount of 0.01% by mass or less.

[0094] Another element in the aluminium alloy according to the first aspect of the present disclosure is zirconium (Zr), present in an amount of from 0 to 1% by mass in relation to the total mass of the aluminium alloy composition. In a preferred embodiment, Zr is present in an amount of 0.5% by mass or less. In a further preferred embodiment, Zr is present in an amount of 0.2% by mass or less. In a further preferred embodiment, Zr is present in an amount of 0.1% by mass or less. In a further preferred embodiment, Zr is present in an amount of 0.05% by mass or less. In a further preferred embodiment, Zr is present in an amount of 0.05% by mass or less.

[0095] Titanium, boron, manganese, zirconium, and chromium are added for grain refinement and to enhance the strength of the aluminium alloys. Even small amounts of these serve as nuclei during solidification of a molten aluminium alloy, so that it solidifies in many places at the same time, which results in a finer structure after extrusion and thus higher strength of aluminium alloy products.

[0096] Another element in the aluminium alloy according to the first aspect of the present disclosure is vanadium (V), present in an amount of from 0 to 0.5% by mass in relation to the total mass of the aluminium alloy composition.

[0097] It is understood that V is added to the aluminium alloy composition in combination with Be to prevent oxidation of the molten metal at the time of melting and casting of the alloy.

[0098] Another element in the aluminium alloy according to the first aspect of the present disclosure is nickel (Ni), present in an amount of from 0 to 1% by mass in relation to the total mass of the aluminium alloy composition.

In a preferred embodiment, Co is present in an amount of 0.3% by mass or less. In a further preferred embodiment, Co is present in an amount of 0.2% by mass or less.

In a further preferred embodiment, Co is present in an amount of 0.01% by mass or less.

[0100] It is understood that both Ni and Co are added to the aluminium alloys to increase the temperature of recrystallization. This is of particular interest in the manufacture of aluminium alloy products by extrusion or other means of wrought applications because the alloy is stabilized at high temperatures. Furthermore, Ni and Co can bind excess Mg thus preventing the precipitation of coarse particles of Mg.

[0101] In another preferred embodiment, the aluminium alloy according to the first aspect of the present disclosure optionally comprises at least one element in an amount of from 0 to 0.5% by mass in relation to the total mass of the aluminium alloy composition, wherein the at least one element is selected from the group consisting of Molybdenum (Mo), Hafnium (Hf), Calcium (Ca), Gallium (Ga), Scandium (Sc), Niobium (Nb), and Cerium (Ce).

[0514] According to one embodiment, the aluminium product according to the second aspect of the present disclosure is an aluminium profile.

[0515] Aluminium profiles find broad application due to their low weight and ideal formability during manufacture. The majority of profiles have longitudinal slots in which sliding blocks can be inserted or swivelled in. These sliding blocks have a threaded hole and can be moved within the groove.

[0516] In addition to sliding blocks, other accessories can be inserted in the aforementioned longitudinal slots: Materials such as acrylic glass, double-webbed sheets, polycarbonate sheets, and the like.

[0520] It is understood that the parts having the thickness in the range as described above is the smallest diameter of the extruded aluminium hollow profile or of the extruded massive aluminium profile.

[0521] In another embodiment, the thickness refers to the thickness of the aluminium alloy part of the extruded aluminium profile. In one embodiment, the thickness of an extruded aluminium hollow profile is the thickness of the walls of the profile.

[0522] In one embodiment, the aluminium alloy of the extruded aluminium profile has a tensile strength Rm of at least 260 MPa.

In a further preferred embodiment, the aluminium alloy of the extruded aluminium profile has a tensile strength Rm of at least 350 MPa.

[0523] In one embodiment, the aluminium alloy of the extruded aluminium profile has a yield strength Rp0.2 of at least 100 MPa. In a preferred embodiment, the aluminium alloy of the extruded aluminium profile has a yield strength Rp0.2 of at least 140 MPa.

In a further preferred embodiment, the aluminium alloy of the extruded aluminium profile has an elongation A of at least 40%. In a further preferred embodiment, the aluminium alloy of the extruded aluminium profile has an elongation A of at least 45%.

[0525] In one embodiment, the aluminium alloy of the extruded aluminium profile has a ratio X between the elongation A and the tensile strength Rm calculated asX=elongation⁢ A [%]tensile⁢ strength⁢ Rm [ MPa]

[0526] In one preferred embodiment, the aluminium alloy of the extruded aluminium product has a ratio X of at least 0.05% / MPa. In a further preferred embodiment, the aluminium alloy of the extruded aluminium product has a ratio X of at least 0.07% / MPa.

In particular, the aluminium alloy products according to the second aspect of the present disclosure provide for advantageous properties when used in the construction of the front of a car, e.g., as longitudinal beam, or in the side impact protection in doors. Furthermore, the aluminium alloy products according to the second aspect of the present disclosure provide for advantageous properties in aluminium lightweight constructions.

[0536] It is understood that the parts having the thickness in the range as described above is the smallest diameter of the drawn aluminium product.

[0537] In another embodiment, the thickness refers to the thickness of the aluminium alloy part of the drawn aluminium product.

The raw aluminium is then heated in a furnace to a temperature melting the aluminium, but not heating the aluminium too high, in particular not above 900° C., in order to avoid the formation of excess oxidation products. It is therefore preferred to heat the raw aluminium to a temperature in the range of from 650 to 850° C. In a further preferred embodiment, the raw aluminium is heated to a temperature in the range of from 750 to 700° C. In a further preferred embodiment, the raw aluminium is heated to a temperature in the range of from 750 to 770° C.

[0552] Once the raw aluminium is melted, Mg and Be are added. As these metals are added in solid form, the temperature of the melt will drop. It is therefore preferred to re-heat the aluminium melt to a previously defined temperature or temperature range, or to maintain the previously defined temperature or temperature range during addition of the metals. Further optional elements, such as Mn, Fe, Cu, Zn and / or Si, may be added during this step.

[0553] The resulting raw aluminium alloy may then optionally be degassed using usual measures. In a preferred embodiment, the degassing may be supported by argon or nitrogen gas as purging gas.

[0617] The present invention as illustratively described in the following may suitably be practiced in the absence of any element or elements, limitation or limitations, not specifically disclosed herein.

[0618] The present invention will be described with respect to particular embodiments and with reference to certain FIGURES but the invention is not limited thereto but only by the claims. Terms as set forth hereinafter are generally to be understood in their common sense unless indicated otherwise.

[0619] Where the term “comprising” is used in the present description and claims, it does not exclude other elements. For the purposes of the present invention, the term “consisting of” is considered to be a preferred embodiment of the term “comprising”. If a group is defined to comprise at least a certain number of embodiments herein, this is also to be understood to disclose a group, which preferably consists only of these embodiments. Furthermore, if a composition is defined using the term “comprising”, it may additionally comprise other elements not explicitly listed, however, not further amounts of an element listed. As such, if, e.g., an aluminium alloy comprises Mg in an amount of 12% by mass, said aluminium alloy may comprise elements other than Mg, however, not additional amounts of Mg, thereby exceeding the amount of 12% by mass.

[0620] The term “about” in conjunction with a numerical value refers to normal deviations of said numerical value. It is to be understood that the term “about” can mean a deviation of ±10%, preferably ±5%, more preferably ±2.5% of said numeric value as indicated.

[0621] Where an indefinite or definite article is used when referring to a singular noun, e.g. “a”, “an” or “the”, this includes a plural of that noun unless something else is specifically stated.

[0622] Terms like “obtainable” or “definable” and “obtained” or “defined” are used interchangeably. This e.g. means that, unless the context clearly dictates otherwise, the term “obtained” does not mean to indicate that e.g. an embodiment must be obtained by e.g. the sequence of steps following the term “obtained” even though such a limited understanding is always included by the terms “obtained” or “defined” as a preferred embodiment.

[0623] As used herein, the terms “impurity” and “impurities” refer to and comprises elements in the alloy which are inevitably present due to, e.g., the manufacturing process of the alloy or the manufacturing process of the raw material(s). An impurity is not explicitly mentioned in the list of elements in the alloy, however, an element may turn from an impurity to an essential element in the alloy. If, e.g., an element is not mentioned in a more general definition of the composition of an alloy, it may be present as an impurity, and the same element may be mentioned as a compulsory compound in a more specific definition of the composition of the alloy.

[0624] The aluminium alloy according to the first aspect of the present disclosure is composed of different components. These components are explicitly listed in the composition of the alloy, or they are part of the impurities present in the alloy. In any case, if a component is defined as an amount in % by mass, the FIGURE reflects the relative amount (as mass) in percent based on the total mass of the alloy composition.

[0625] As used herein, the terms “tensile strength” and “ultimate tensile strength” are used interchangeably. The tensile strength may be abbreviated as “Rm”. Methods for determining the tensile strength are known to the skilled person. As used herein, the tensile strength Rm is the maximum stress that a material can withstand while being stretched or pulled before breaking.

[0626] As used herein, the terms “yield strength” and “yield tensile strength” are used interchangeably. The yield strength may be abbreviated as “Rp0.2”. Methods for determining the yield strength are known to the skilled person. As used herein, the tensile strength is the stress corresponding to the yield point at which the material begins to deform plastically. The yield point is the point on a stress-strain curve that indicates the limit of elastic behaviour and the beginning of plastic behaviour. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be permanent and non-reversible and is referred to as plastic deformation.

[0627] As used herein, the term “elongation” abbreviated as “A” is the elongation at fracture and indicates the permanent elongation of a tensile specimen after fracture, in relation to the initial gauge length of the tensile specimen. In other words, the elongation A is the permanent change in the length ΔL of a specimen in a tensile test after fracture has occurred in relation to the initial gauge length L0 of the specimen.

[0628] As used herein, the terms yield strength Rm, tensile strength Rp0.2, elongation A, and the ratio X refer to the aluminium alloy of the aluminium product. In other words, terms yield strength Rm, Rp0.2, elongation, and the ratio X are measured on the aluminium part of the aluminium product.

[0629] The yield strength Rm, tensile strength Rp0.2, elongation A of the aluminium alloys are determined in accordance with DIN 50125:2009 at 23° C.

[0630] As used herein, the term “extrusion” is a process used to create objects of a fixed cross-sectional profile by pushing a preheated billet of an aluminium alloy according to the first aspect of the present disclosure through a die of the desired cross-section. Extrusion may be continuous. In continuous extrusion, a theoretically indefinitely long aluminium alloy product can be produced. Extrusion may be semi-continuous. In semi-continuous extrusion, many pieces of identical size can be produced.

[0631] As used herein, the terms “aluminium profile” and “extruded aluminium profile” are used interchangeably. The term “extruded” means that the aluminium profile has been manufactured by extrusion as described above.

[0632] The term “hollow” as used herein, means that at least part of the aluminium hollow profile is not massive but has a hollow cross-section. In other words, the aluminium hollow profile has a hole or an empty space inside. The hollow part is filled with air.

The cross-section is determined by the die and / or mandrel used in the manufacturing, e.g., extrusion, process.

[0635] The terms “wrought applications” and “wrought process” are used interchangeably. As used herein, the term wrought application means any process which involves the shaping of metal with a high degree of shaping. In other words, a wrought application is the beating of a piece of metal into a shape by tools. One example of wrought application is forging. Another example of wrought application is semi-solid shaping.EXAMPLESExample 1: Manufacture of Aluminium Alloys

[0636] All aluminium alloys were prepared in a resistance-heated crucible furnace (Nabertherm, model K40 / 12). For the preparation of a 50 kg of raw aluminium melt, the raw aluminium (with 0.15% by mass or less of total impurities; obtained from Adial, Adriers, France) was added into the furnace over a period of 1 h to result in a molten raw aluminium.

[0637] The raw aluminium was heated to 720 to 750° C. and the respective amounts of Mg (from DEUMU Deutsche Erz-und Metall-Union GmbH, Germany, pure magnesium, at least 99.8%) and Be (added as pellets of AlBe, containing 5% by mass of Be, the remainder being Al, from Hoesch Metals, Niederzier, Germany) were added. After re-heating to 720 to 750° C., the melt was de-gassed for 10 minutes with Argon gas as purging gas using an injection lance.

[0638] Then, at a temperature in the range of 650 to 750° C., Ti and B are added as bars containing Ti and B in a ratio of 5:1 (added as pellets of AITi5B1, containing 5% by mass of Ti, 1% by mass of B, the remainder being Al, from Foseco-Vesuvius, Germany). The bars are stirred into the liquid alloy, and immediately after mixing, the furnace is tilted and the liquid alloy is cast into a respective mold to provide an aluminium alloy billet.TABLE 1Composition of aluminium alloy. All amounts are given in % bymass in relation to the total mass of the aluminium alloy. Thebalance to the compositions disclosed in Table 1 is aluminium.No.MgTiBeBSiFeMnCuImpurities18.260.0150.0050.0030.0990.0860.0050.0040.066211.400.0710.0160.0140.0050.0800.0040.0010.084Example 2: Manufacture of Aluminium Hollow Profiles

[0639] The aluminium alloy billets No. 1 and No. 2 of example 1 were preheated to a temperature in the range of from 400 to 450° C. and placed into an extrusion press (from SMS group, Germany; maximum pressing force of 9000 kN) for direct extrusion.

[0640] The extrusion process results an aluminium hollow profile with 30 mm height (also referred to the narrow side S), 60 mm width (also referred to as the broad side B), and a wall thickness s of 3 mm as depicted in FIG. 1.Example 3: Heat Treatment

[0641] The aluminium hollow profiles of example 2 were investigated for the mechanical properties with and without heat treatment.

[0642] The aluminium hollow profiles were heated to a temperature of 450° C. for 4 h in a furnace and then cooled to room temperature.Example 4: Mechanical Properties

[0643] For evaluation of the mechanical properties, dumbbell-shaped samples were cut out of the narrow side S and the broad side B of the aluminium hollow profiles according to examples 2 and 3.

[0644] Both the heat treated and not heat treated samples were subjected to tests determining the tensile strength (Rm), the yield strength (Rp0.2) and the elongation (A). The measuring length was 30 mm for all samples having a thickness of 3 mm. All test results are summarized in Table 2 below.

[0645] The samples were prepared and tested in accordance with DIN 50125:2009 at room temperature (23° C.).TABLE 2Mechanical properties of alloys No. 1 and No. 2No.heat treatedRm [MPa]Rp0.2 [MPa]A [%]1No308.4182.051.6Yes269.4103.247.72No340.8190.426.4Yes368.4187.248.9

[0646] It can be seen from the above test results that the samples of the extruded aluminium hollow profiles of alloys No. 1 and No. 2 show excellent mechanical properties, in particular in terms of yield strength Rm, tensile strength Rp0.2, and elongation A. In particular, the samples have both high yield strength and elongation at the same time; with and without heat treatment.Example 5: Manufacture of a Drawn Aluminium Product

[0647] An aluminium alloy billet of the composition of table 3 was provided according to the method of example 1.TABLE 3Composition of aluminium alloy. All amounts are given in % bymass in relation to the total mass of the aluminium alloy. Thebalance to the compositions disclosed in Table 3 is aluminium.imp.imp.No.MgTiBeMnFeCrZrind.#tot.#311.070.01620.00390.0320.04750.0.00620.0068<0.05<0.15#“imp. ind.” refers to the amount of each individual impurity in % by mass contained in aluminium alloy No. 3; “imp. tot.” refers to the amount in % by mass of all impurities contained in aluminium alloy No. 3 combined.

[0648] The diameter of the aluminium alloy billet was reduced to >65 mm by turning on a lathe and extruded to provide an aluminium raw wire having a diameter of 2.00 mm. One end of said aluminium raw wire was shrunk to a diameter that is smaller than the diameter of a drawing die.

[0649] The aluminium raw wire was placed into a drawing die having a diameter of 1.90 mm and a die angle of 12°, and pulled through said die to provide a drawn aluminium product having a diameter of 1.9 mm.

[0650] The above process steps were repeated with drawing dies having a diameter of 1.80 mm, then 1.70 mm, then 1.60 mm, then 1.50 mm, the 1.40 mm, then 1.30 mm, then 1.25 mm, then 1.20 mm to yield a drawn aluminium product having a diameter of 1.20 mm. Each of the drawing dies has a doe angle of 12°.

[0651] Between the steps of wire drawing, no intermediate annealing was performed. The drawn aluminium product was not subjected to a heat treatment.

[0652] The sample was then tested at room temperature (23° C.).TABLE 4Mechanical properties of drawn aluminium product of alloy No. 3No.Rm [MPa]A [%]3382.323

[0653] As a comparative example, one end of the aluminium raw wire of alloy No. 3 having a diameter of 2.00 mm was shrunk to a diameter that is smaller than 1.70 mm. Then, the aluminium raw wire was placed into a drawing die having a diameter of 1.70 mm and a die angle of 12°, and pulled through said die. After 10 cm of drawing, the wire snapped. No wire could be prepared.Items
