7075 T6 vs. T6511
7075 T6 vs. T6511
(OP)
I understand that T6511 is stress-relieved by stretching and artificially aged, whereas T6 is simply artificially aged, but theoretically they have the same mechanical (tensile) properties. What is the difference between these materials in terms of design? If a part usually manufactured in T6511 was instead made in T6, what differences in performance would be expected? Would the T6 part be more prone to cracks or stress corrosion due to the fact it is not stress-relieved?

Like swall states, some raw stock comes only as T6, some only as T651. In the end, it doesn't matter but allowing for either means your purchasing group can pick the less expensive of the two, or the one that can be delivered quicker.

By the way, I just joined here and I really appreciate the advice. Thanks.

You should also realize that while it isn't explicitly stated in ANSI H35.1, the stress relieved tempers such as -T6511 are a subset of the -T6 temper. That's why I push our drawings to call out -T6, because then if our vendor gives us -T6511, it's per print.
