7075 forged block

7075 forged block is a cold-treated forging alloy, which belongs to the Al-Zn-Mg-Cu series of super-hard aluminum. 7075 alloy has been used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry. Ultra-high-strength deformed aluminum 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; aluminum 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 just-quenched state is slightly lower than 2A12 in the same state. It is slightly better than 7A04. The static fatigue of the sheet is sensitive to notches, and the stress corrosion performance is better than 7A04. Among them, the 7075-T651 state is especially the top grade and is known as aluminum. The most excellent product among alloys has high strength, far better than mild steel. 7075 forged block
With good mechanical properties and anode reaction, it is a typical aluminum alloy material for aerospace and military industry.
