7150 is a high-strength heat-treatable alloy with extremely high strength and resistance to spalling corrosion and stress corrosion cracking. Commonly used in aircraft structural parts for plate extrusions, free forgings and die forgings. The 7 series aluminum alloy belongs to Al-Zn-Mg-Cu series super-hard aluminum, which is an ultra-high-strength deformed aluminum alloy that has been widely used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. Its characteristics are: 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 covered with aluminum or other Protective use. Two-stage aging can improve the alloy's resistance to stress corrosion cracking. The plasticity in the annealed and hardened state is slightly lower than 2A12 in the same state. It is slightly better than 7A04, the plate is subject to static fatigue. The notch is sensitive, and the stress corrosion performance is better than 7A04. The density is 2.75.
