Description

technical field [0001] The invention relates to an aluminum alloy, in particular to an aluminum alloy for high-toughness coating equipment and a preparation method thereof. Background technique [0002] Magnesium-aluminum alloy is an alloy that cannot be strengthened by heat. It has medium strength, good processing performance and corrosion performance, and has high corrosion resistance in industrial areas and marine exposure. It is widely used in the production of aviation and aerospace components (skin, frame or spars, etc.). The mechanical properties of magnesium-aluminum alloy increase with the increase of Mg content, but its corrosion resistance deteriorates, plasticity decreases, and cracks are prone to appear during the preparation process. Among the existing aluminum alloy materials, there are very few materials suitable for vacuum coating, and they cannot meet the process requirements, and are prone to corrosion and fracture. Therefore, the materials used for coat...
