7075 T6/T62/T7351 Aircraft Aerospace Aviation Aluminum Alloy Sheet Plate

Product Description

7075 T6 T62 T7351 aluminum alloy sheet plate Product Description
7075 T6 T62 T7351 aluminum alloy sheet plate is currently the most widely used 7 * * * aviation Aluminum Alloy, main supply varieties of aluminum or aluminum, heat treatment condition of O, T6, T73, T76. The static strength of T6 is the highest, the ductility is the lowest and the fatigue is the worst. It is sensitive to stress corrosion cracking, and toughness decreases with the decrease of temperature. So the T6 state is not applied to cryogenic working parts. T73 has the lowest state strength, but has high fracture toughness and excellent resistance to stress corrosion cracking and denudation. The performance of T76 is between T6 and T73. Compared with T6 state, it has low strength but good resistance to stress corrosion. Compared with T73 state, its strength is high, but its stress corrosion resistance is poor.
