Product introduction

7A09 aluminum plate belongs to al-zn-mg-cu superhard aluminum, which has been used in the aircraft manufacturing industry since the late 1940s and is still widely used in the aviation industry today.7A09 aluminum plate is characterized by good plasticity after solid solution treatment, especially good heat treatment strengthening effect, high strength below 150℃, and a particularly good low temperature strength;Poor welding performance;There is a tendency of stress corrosion cracking;To be used with aluminum coating or other protective treatment.The resistance to stress corrosion cracking can be improved by double aging.The plasticity of 2A12 aluminum plate is slightly lower than that of 7A04 aluminum plate in the same state in annealing and just quenched state, and the static fatigue of the plate is slightly better than that of 7A04 aluminum plate.

USES:

7A09 aluminum plate is mainly used for the manufacture of aircraft structures and other high stress structures requiring high strength and corrosion resistance, such as aircraft, lower wing facing panels, truss bars, etc.Good plasticity after solid solution treatment, good heat treatment strengthening effect, good strength below 150 degrees, and has particularly good low temperature strength, poor welding performance, a tendency to stress corrosion cracking.7A09 aluminum plate is also widely used in mold processing, mechanical equipment, fixtures, aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf ball head, shoe mold, paper mold, foaming molding mold, dewaxing mold, mechanical equipment, for the production of high-end aluminum alloy bicycle frame.In 2014, 7A09 aluminum plate was used as the body material of the smartphone OPPO N3 for the first time.
