7075 aluminum alloy

7075 aluminum alloy is a cold-treated forging alloy with high strength, far better than mild steel. 7075 is one of the strongest alloys commercially available. General corrosion resistance, good mechanical properties and anodic reaction. Smaller grains allow for better deep drilling performance, enhanced tool wear resistance and distinctive thread rolling. Zinc is the main alloying element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the heat treatment effect of the alloy far better than that of the aluminum-zinc binary alloy. Increasing the content of zinc and magnesium in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and exfoliation corrosion will decrease accordingly. After heat treatment, it can achieve very high strength characteristics. 7075 ingredients are generally added with small amounts of copper, chromium and other alloys, among them, the 7075-T651 aluminum alloy is a top class known as the superior product for aluminum alloys. It has high strength and is far superior to any mild steel. This alloy has good mechanical properties and anodic reaction. Representative uses include aerospace, mold processing, mechanical equipment, tooling fixtures, especially for manufacturing aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
