The 7-series aluminum alloy metal Al-Zn-Mg-Cu is a super-hard aluminum alloy. This alloy has been used in the aircraft manufacturing industry in the late 1940s and is still an ultra-high-strength deformed aluminum alloy 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 coated with aluminum or other materials Protective handling used. Dual-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and freshly quenched states is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04. The plate's static fatigue and notch sensitivity are better than that of 7A04. The density is 2.85g/cm3.
