7150 aluminum plate for wing panels of aircraft

　　7150 aluminum plate for wing panels of aircraft belongs to the Al-Zn-Mg-Cu super-hard aluminum. It is an ultra-high-strength heat-treatable deformed aluminum alloy with extremely high strength and resistance to spalling corrosion and stress corrosion cracking. The alloy has been used in the aircraft industry in the late 1940s, and is still widely used in the aviation industry. Commonly used in aircraft structural parts for medium and thick plate extrusions, free forgings and die forgings. The characteristics of 7150 aluminum plate are that it has good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; aluminum cladding is required Or other protection processing use. Two-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and as-quenched state is slightly lower than 2A12 in the same state and slightly better than 7A04. The static fatigue of the sheet is sensitive to notches, and the stress corrosion performance is better than 7A04. The density is 2.75.
