aircraft aluminum plate

The main alloy element of 7075 is zinc, which is very strong and has good mechanical properties and anodic reaction. It is mainly used in the manufacture of aircraft structures and other high stress structural parts requiring high strength and corrosion resistance, such as the upper and lower airfoil wall panels and trusses. Good plasticity after solution treatment, good heat treatment strengthening effect, good strength below 150 degrees, and has a particularly good low temperature strength, poor welding performance, the tendency of stress corrosion cracking. Also widely used in mold processing, mechanical equipment, fixtures, etc.
