The temper T73 after solution treatment reduces the material strength by 1 0 %-15 % , and the corrosion resistance is significantly improved . The 7075T73 aluminum round bars are mainly used for high-strength and corrosion-resistant rivet materials.

T73511 means solution treatment (quenching), stretching a certain amount to eliminate internal stress (1%~3% for extruded tubes, rods, profiles, 0.5%~3% for drawn pipes) and then over artificial aging until the material has the most excellent resistance to stress corrosion cracking. Straightening will be helpful to meet the standard dimensional deviation accuracy. Tensile Strength: >68 ksi , Yield Strength: >56ksi , Elongation: >10%.
