The 7075T6 7075T651 7075T6511 aluminum round bars can be used if no precision requirement for dimensional stability and elastic allowance.

T6 temper means solution treatment (quenching) and artificial aging. 7075 T6 aluminum round bar has the highest state strength and low fracture toughness. Its tensile strength is 74,000-78,000 psi (510-538 MPa), the yield strength is 63,000-69,000 psi (434-476 MPa), and the elongation is 5-8%.

T651 temper means solution treatment (quenching) , stretching a certain amount to eliminate internal stress (1%~3% for cold finished bars), and then artificial aging. The 7075T651 aluminum round bars have tensile strength 67,000-78,000 psi (462-538 MPa), yield strength 54,000-67,000 psi (372-462 MPa), and elongation 3-9%.
