7075 is mainly used to manufacture aircraft structures and other high-stress structural components with high strength and corrosion resistance, such as aircraft upper, lower wing panels, trusses, etc. After solid solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, especially good low temperature strength, poor weldability and stress. Corrosion cracking tendency
1 and 7075 aluminum alloy is a cold treatment forging alloy, high strength, far better than mild steel. 7075 is one of the most powerful commercial alloys. The heat treatment can achieve very high strength characteristics. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075-T651 aluminum alloy is the most superior one. It is known as the best product of aluminum alloy, with high strength and far superior to any mild steel. The alloy has good mechanical and anodic reaction.
