7075 aluminum alloy is a commonly used alloy. It contains zinc and magnesium, but it cannot be welded. Moreover, its corrosion resistance is quite poor.Zinc is the main alloying element in this series, and a little magnesium alloy enables the material to be heated to very high strength properties.This series of materials generally add a small amount of copper, chromium and other alloys, high strength, so very suitable for aircraft framework and high strength precision components accessories. Chalco Aluminum has been making metric 7075 aluminum plate for more than 10 years. Our metric 7075 aluminum plate has been widely used in aviation and military industry. Our products are characterized by good plasticity after solid solution treatment and excellent heat treatment strengthening effect.To avoid the tendency of stress corrosion cracking completely, the two-stage aging treatment greatly improves the ability of alloy to resist stress corrosion cracking.
