7075 aluminum alloy is a cold treated forging alloy with high strength, which is much better than mild steel. 7075 is one of the most powerful alloys commercially available. General corrosion resistance, good mechanical properties and anodic reaction. Fine grains make the deep drilling performance better, the wear resistance of tools is enhanced, and the thread rolling is more different. Zinc is the main alloy 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 aluminum zinc binary alloy. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its ability to resist stress corrosion and spalling corrosion will decrease. After heat treatment, it can achieve very high strength characteristics. 7075 materials are generally added with a small amount of copper, chromium and other alloys. 7075-T651 aluminum alloy is particularly top-grade. It is known as the best product of aluminum alloy, with high strength and far better than any mild steel. The alloy has good mechanical properties and anodic reaction. Representative applications include aerospace, mold processing, mechanical equipment, tooling and fixtures, especially for manufacturing aircraft structures and other high stress structures requiring high strength and strong corrosion resistance.
