7075 t6 aluminum billet

Dec 17, 2021

The 7XXX series aluminum alloy belongs to the Al-Zn-Mg-Cu series super-duralumin. The 7075 t6 aluminum billet is a high-strength deformed aluminum that has been used in the aircraft industry in the late 1940s and is still widely used in the aviation industry. alloy. It is characterized by 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; need to be coated with aluminum or other Protection processing use. Two-stage aging can improve the alloy's ability to resist stress corrosion cracking.

Alloy characteristics of 7075 t6 aluminum billet:
1. High-strength heat-treatable alloy.
2. Good mechanical properties.
3. Good usability.
4. Easy to process and good wear resistance.
5. Good corrosion resistance and oxidation resistance.
