7A09 T62 aluminum alloy plate

7A09 aluminum plate main features and application scope:

7A09 aluminum alloy belongs to Al-Zn-Mg-Cu series super-durable aluminum. This alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft industry in the late 1940s and is still widely used in the aviation industry.

7A09 aluminum sheet is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150℃, and particularly good low temperature strength; poor welding performance; tendency to stress corrosion cracking; need to be coated with aluminum or other Protective use. Two-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and just-quenched state is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04 aluminum alloy, the static fatigue of the plate. The notch is sensitive, the response force corrosion performance is better than 7A04 aluminum alloy.
