7075 aluminum is a kind of cold treatment forging alloy with high strength and hardness, far better than mild steel. 7075 aluminum is one of the most powerful commercial alloys. It has common corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance enhanced, the thread rolling more different, the density requirement is smaller, the hardness requirement is higher.
7075 alloy belongs to Al Zn mg Cu super hard aluminum. It has been used in aircraft manufacturing industry since the late 1940s and is still widely used in aviation industry. It is characterized by good plasticity after solution treatment, especially good heat treatment strengthening effect, high strength below 150 ℃ and especially good low temperature strength; The welding performance is poor; There is a tendency of stress corrosion cracking; It needs to be protected by aluminum coating or other treatment. Two stage aging can improve the stress corrosion cracking resistance of the alloy. The results show that the plasticity of the annealed and quenched sheet is slightly lower than that of 2A12 and better than 7A04. The static fatigue, notch sensitivity and stress corrosion resistance of the sheet are better than those of 7A04. Among them, 7075-T651 is the best product in aluminum alloy with high strength and far better than soft steel. The alloy has good mechanical properties and anodic reaction, and is a typical aluminum alloy material for aerospace and military industry.

7075 is an aluminum alloy with zinc as the main alloying element, but sometimes a small amount of magnesium and copper are added. Among them, super hard aluminum alloy is a kind of alloy containing zinc, lead, magnesium and copper, which is close to the hardness of steel and can be strengthened by heat treatment. It is a high strength and heat treatable alloy with ordinary corrosion resistance and good mechanical properties. Aluminum 7075 is a cold treatment forging alloy with high strength, far better than mild steel. 7075 aluminum alloy is one of the most powerful commercial alloys. General corrosion resistance, good mechanical properties and anodic reaction. The fine grain makes the deep drilling performance better, the tool wear resistance enhanced, and the thread rolling is more different from the heavy one.
Zinc is the main alloying element in 7075. Adding magnesium to the alloy containing 3% - 7.5% zinc can form mgzn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than that of Al Zn binary alloy.
With the increase of Zn and Mg content in the alloy, the tensile strength will be further improved, but the resistance to stress corrosion and exfoliation corrosion will be decreased.
After heat treatment, very high strength characteristics can be achieved. 7075 materials are generally added with a small amount of copper, chromium and other alloys. Among them, 7075t651 aluminum alloy is particularly high-grade. It is known as the best aluminum alloy product with high strength and far better than any mild steel.
