Aluminum 7075 Drawn Seamless Tube
O.D max : 70mm / 2.76"
7075 Aluminum
7075 is the other "aircraft grade" aluminum. Its principal alloying ingredients are zinc and copper, this makes it one of the highest-strength aluminum alloys that are available. In fact, 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.
