Problems solved by technology

With the improvement of technical requirements for products, traditional 6-series aluminum alloys have been difficult to meet the performance requirements of high-end products, especially in terms of anti-drop deformation, bending deformation and other indicators
[0004] The 7-series aluminum alloy has obvious advantages over the 6-series aluminum alloy in terms of strength, but the anodized surface quality of the aluminum alloy is not as fine as the 6-series aluminum alloy, and it is prone to

Abstract

The invention discloses an aluminium alloy material and a preparation method thereof. The aluminium alloy material comprises the following steps by weight percent: 3%-10% of zinc, 0.5%-3% of magnesium, 0.1%-0.5% of copper, less than 0.1% of silicon, less than 0.2% of iron, less than 0.15% of chromium, less than 0.03% of titanium, less than 0.15% of total impurities (with less than 0.05% of singe impurity element) and the balance of aluminum.

Description

technical field [0001] The invention relates to the technical field of alloy materials, and more specifically, to an aluminum alloy material and a preparation method. Background technique [0002] Aluminum alloy materials are widely used in automobiles, electronics, aerospace and other fields. Compared with other materials, aluminum alloy has the characteristics of low density, high strength, good electrical and thermal conductivity, and excellent surface decoration performance. [0003] Due to the excellent anodic oxidation coloring ability of aluminum alloy materials, it has been more and more widely used in the manufacture of mobile phones and smart consumer electronics. With the improvement of technical requirements for products, the traditional 6-series aluminum alloys have been difficult to meet the performance requirements of high-end products, especially in terms of anti-drop deformation, bending deformation and other indicators. [0004] The 7-series aluminum allo...
