7075 is Al-Zn-Mg-Cu superhard aluminum alloy, which has been used in aircraft industry since the end of 1940s and is still widely used in aviation industry. It is characterized by good plasticity after solution treatment, especially good strengthening effect of heat treatment, high strength below 150 °C, especially good low temperature strength, poor welding performance, stress corrosion cracking tendency; Need to be coated with aluminum or other protective treatment. Two-stage aging can improve the resistance of the alloy to stress corrosion cracking. The plasticity in the annealed and quenched state is slightly lower than in the same state 2 a 12. Slightly better than 7 a 04, plate static fatigue. Notch sensitivity, stress corrosion cracking better than 7A04.
6082 aluminium plate mainly used in transportation and structural engineering industries, such as bridges, cranes, roof frames, transport planes, transport ships, etc.
6082 aluminium plate can be strengthened by aging treatment, with good extrusion and forging properties, and good anodizing properties.
