Aluminum 7075-T651/T65151/T73/T7351 Product Guide
Overview
7075 is the other "aircraft grade" aluminum that is carried by OnlineMetals. Its principal alloying ingredients are zinc and copper, which make it one of the highest-strength aluminum alloys that are available. In fact, its typical strength in the T651 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.
