Problems solved by technology

Aluminum foil is a relatively perfect packaging material with many excellent properties. It has fully demonstrated its broad application prospects in many fields. Aluminum foil is a soft aluminum alloy film, which is widely used in food, beverages, cigarettes, medicines, and photo bases. , household goods and other fields, usually used as packaging materials, electrolytic capacitor materials, heat insulation materials for buildings, vehicles, ships, houses, etc. However, the existing aluminum foil will form wrinkles when it is rolled or unrolled. Due to the insufficient ductility of the aluminum alloy used to make the aluminum foil, the tension of the aluminum foil is not enough to flatten the foil surface

Embodiment Construction

[0010] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0011] An aluminum alloy used to make aluminum foil, in addition to containing 87.8% aluminum, it also contains magnesium, copper, zinc and tungsten, the magnesium content is 8%, and the content is percentage by weight. The added magnesium makes the aluminum alloy It has good ductility and softness, and enhances its machinability.

[0012] In addition, the copper content is 1.05%.

[0013] In addition, the zinc content is 3%.

[0014] In addition, the tungsten content is 0.15%.

[0015] In addition, the content of other components contained in the alloy is 0.1%.

[0016] The aluminum alloy used to make the aluminum foil has low density, high tensile strength, high elongation, and good ductili...

Abstract

The invention discloses an aluminum alloy for manufacturing aluminum foils. The aluminum alloy comprises 83.1 to 94.4 weight percent of aluminum, 3 to 10 weight percent of magnesium, and the balance of copper, zinc and tungsten. The aluminum alloy for manufacturing the aluminum foils has the advantages of low density, high tensile strength, high elongation and high ductility.

Description

technical field [0001] The invention relates to the application field of aluminum profiles, in particular to an aluminum alloy used for manufacturing aluminum foil. Background technique [0002] With the improvement of people's living standards and the development of tourism, the demand for beverages such as beer and soda and canned food is increasing day by day, all of which require modern packaging and decoration to facilitate competition in the international market. Aluminum foil is a relatively perfect packaging material with many excellent properties, and it has fully demonstrated its broad application prospects in many fields. Aluminum foil is a soft aluminum alloy film, which is widely used in food, beverages, cigarettes, medicines, and photo substrates. , household goods and other fields, usually used as packaging materials, electrolytic capacitor materials, heat insulation materials for buildings, vehicles, ships, houses, etc. However, the existing aluminum foil wil...
