7075 aluminum process performance: 7075 aluminum plate is Al-Zn-Mg-Cu series super-hard aluminum, 7075 alloy has been used in the aircraft industry in the late 1940s, and is still widely used in the aviation industry for ultra-high strength deformation Aluminum alloy.

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 machining or other Protective use. Two-stage aging can improve the alloy’s resistance to stress corrosion cracking. The plasticity in the annealed and freshly quenched state is slightly lower than 2A12 in the same state.

It is slightly better than 7A04, and the plate is subject to static fatigue. The notch is sensitive, and the stress corrosion performance is better than 7A04. Among them, the 7075-T651 state is the best, and it is known as aluminum The best product in the alloy has high strength and is far better than mild steel. This alloy has good mechanical properties and anode reaction, and is a typical aerospace aluminum alloy material.
