7075 aluminum alloy is a cold treatment forged alloy; with temper T651, its internal stress has been eliminated and it will not deform and warp after machining; all super size & thickness 7075 aluminum plates have been tested by supersonic wave so as to guarantee that there is no trachoma & impurity; it has high heat conductivity which can reduce shaping time and improve work efficiency; it contains Zn used for aerospace industry, belonging to Al-Zn-Mg-Cu alloy; it is of hard aluminum alloy, with good abrasive property; it can reach to extremely high strength by heat treatment.
Tensile Strength ?b( MPa): ≥540
Yiled Strength ?0.2(MPa): ≥460
Elongation δ5(%): ≥8
1. Superior machinability;
