The most popular temper designation for 7075 aluminum flat bars is T6 temper. With a tensile strength of up to 540 MPa and yield strength of up to 480 MPa, T6 temper 7075 is comparable to some steels. The T6 temper 7075 is made through solution heat treatment, homogenization, and quenching. The result is an alloy with the highest strength possible. Such peak strength makes the 7075-T6 aluminum flat bars applicable in defense equipment, meter shafts, aircraft shafts, and so on.
