7075 T6 Aluminum Bar

7075 Aluminum is a very high-strength material used for highly stressed structural parts. The T7351 temper offers improved stress-corrosion cracking resistance. It has a strength level equal to or exceeding mild steel. It has good machinability and excellent finishing characteristics. It is hardenable by heat treatment and/or cold working.

7075 is the other “aircraft grade” aluminum that OnlineMetals carries. Its principal alloying ingredients are zinc and copper, which make it one of the highest-strength aluminum alloys that are available. Its typical strength in the T6 temper is higher than most mild steels. 7075 also has average to good ratings for machinability, corrosion resistance, and anodizing response. Like 2024, however, it is not considered to be weldable. It is typically used in aircraft, missiles, spacecraft, and other defense applications.
