Aluminum 7075-T6; 7075-T651

Subcategory:

7000 Series Aluminum Alloy; Aluminum Alloy; Metal; Nonferrous Metal

Composition Notes:


A Zr + Ti limit of 0.25 percent maximum may be used with this alloy designation for extruded and forged products only, but only when the supplier or producer and the purchaser have mutually so agreed. Agreement may be indicated, for example, by reference to a standard, by letter, by order note, or other means which allow the Zr + Ti limit.
Aluminum content reported is calculated as remainder.
Composition information provided by the Aluminum Association and is not for design.
