7075 Aluminum Plate
Aluminum is Al - zinc - 7075 Mg - Cu superhard aluminium, alloy 7075 is in the late 1940 s has been applied in aircraft manufacturing industry, is still widely used in aviation industry deformation of ultra high strength aluminum alloy. Its characteristic is that after solid solution treatment and plastic, heat treatment reinforcement effect is very good, under 150 ºC has high strength, and has very good strength at low temperature; Welding performance is poor; There is stress corrosion cracking tendency; Need to the package aluminum or other protective treatment. Two-stage aging alloy can be improved the ability of resistance to stress corrosion cracking. After annealing and quenching condition of plastic was slightly lower than the same state of 2 a12) was slightly better than that of 7 a04, plank of static fatigue. Notch sensitivity, stress corrosion performance is better than that of 7 a04, of which 7075 - T651 state is top grade, is praised as the most excellent products in aluminum alloy, high intensity, far more than mild steel. The alloy has good mechanical properties and the anode reaction, is a typical aerospace aluminum alloy material.
