Embodiment 1 to Embodiment 4

[0088] The multilayer aluminum composite sheet 100 formed according to Examples 1 to 4 was subjected to solution treatment at 480° C. for 4 hours and water cooling. Thereafter, age hardening is performed under various conditions.

Embodiment 5 to Embodiment 8

[0090] The multilayer aluminum composite sheet 100 formed according to Examples 5 to 8 was subjected to solution treatment at 520° C. for 4 hours and to water cooling. Thereafter, age hardening is performed under various conditions.

[0091] according to Figure 5 Operation 60 in and as in Figure 6 As shown in (g), the composite sheet 100 that has been subjected to solution treatment may be subjected to age hardening using heat treatment.

[0092]Age hardening is the process by which a metallic material hardens at an appropriate temperature for a period of time and changes from an original unstable state to a stable state. In this process, the atoms in the metallic material arrange into metallic crystals. Age hardening includes two types: room temperature age hardening and artificial age hardening. The former causes the atoms in the material to move at room temperature, and the latter uses heat to cause the atoms to move. According to an embodiment of the present disclos...

Embodiment 1

[0095] In Example 1, the multilayer aluminum composite sheet 100 that had been subjected to solution treatment at 480° C. for 4 hours and water cooling was age-hardened at 120° C. for 24 hours. It can be confirmed that the obtained multilayer aluminum composite sheet 100 exhibits a yield strength of 372 MPa.

Abstract

According to an embodiment, an aluminum clad sheet and method for manufacturing the same are disclosed. The anodizable aluminum clad sheet may comprise a base material including a 7xxx-series aluminumalloy and a coat material including a 6xxx-series aluminum alloy or a 1xxx-series aluminum alloy disposed on one or both front and back surfaces of the base material, wherein the 7xxx-series aluminumalloy includes 4.0% to 8.0% of zinc (Zn) relative to a total weight of the aluminum clad sheet, and 1.0 % to 3.0 % of magnesium (Mg) relative to the total weight of the aluminum clad sheet, and the rest being aluminum (Al) and at least one other impurity. According to an embodiment, a method for manufacturing the aluminum clad sheet may enhance the adhesion strength of the clad sheet by employingthermal treatment after forming the clad sheet and may age-harden the clad sheet without deteriorating strength, thereby achieving superior surface and processing properties.

Description

technical field [0001] Various embodiments of the present disclosure generally relate to anodizable aluminum composite sheets and methods of making the same. Background technique [0002] Aluminum is a light metal commonly used in industrial applications for countless purposes. The aluminum alloy is an alloy whose main metal is aluminum (Al). Typical alloying elements accompanying aluminum are copper, magnesium, manganese, silicon, tin and zinc. [0003] Due to their extraordinary specific strength, most aluminum alloys have widespread applications in the aerospace industry, and their advantages in thermal conductivity, reflectivity, corrosion resistance, and / or machinability have led to their use for military or civilian purposes (e.g., There is considerable demand for defense or civilian items such as automobiles and aircraft. There are two main classifications of aluminum alloys, namely, cast alloys and wrought alloys, which are further subdivided into heat treatable a...
