Aluminum alloy aa7075 sheet is a cold treatment forging alloy, high strength, high hardness, far better than soft steel. 7075 aluminum plate is one of the commercial power alloy, ordinary corrosion resistance, good mechanical properties and anodic reaction. Fine grains make depth drilling performance better, tool wear resistance enhanced, thread rolling more with heavy different, in the density required less, hardness requirements are relatively high metal materials.
Aluminum alloy aa7075 sheet is Al-Zn-Mg-Cu system super hard aluminum, its characteristics are, good plasticity after solid solution treatment, heat treatment strengthening effect is particularly good, in 150 ℃ below the high strength, and has a particularly good low temperature strength; welding performance is poor; there is a tendency of stress corrosion cracking; need to be used by cladding aluminum or other protective treatment. Double-stage aging can improve the alloy's ability to resist stress corrosion cracking. In the annealed and just quenched state of plasticity is slightly lower than the same state of 2A12. slightly better than 7A04, the plate of static fatigue. Notch sensitive, stress corrosion performance is better than 7A04, of which 7075T651 is particularly good, known as the best products in aluminum alloy, high strength, far better than soft steel. This alloy has good mechanical properties and anodic reaction.
Double-stage aging improves the alloy's resistance to stress corrosion cracking. The plasticity in the annealed and freshly quenched state is slightly lower than that of 2A12 in the same state. Notch sensitive, stress corrosion performance is better than 7A04, of which 7075-T651 state is particularly good, known as the excellent product of aluminum alloy, high strength, far better than soft steel.
