Difference between AA6061-T651 and T6511
Difference between AA6061-T651 and T6511
(OP)
I have a query which I hope someone can help with. I recently received an enquiry from a customer for AA6061-T6511 or alternatively T651 in accordance with ASTM B210. However, on checking the a/m ASTM specification, there was no mention of either T651 or T6511.
Can someone enlighten me on this? Preferably, reference to a specification would be appreciated. Thanks.

T6511 is the same as T651 but "may receive minor straightening after stretching to comply with standard tolerances."
The 2003 standards book (and many others from AA) is available at http://www.aluminum.org/Template.cfm?Section=BookStore&Template=/Ecommerce/ProductDisplay.cfm&Productid=339
