7049A-T6510 Aluminum
7049A-T6510 aluminum is 7049A aluminum in the T6510 temper. To achieve this temper, the metal is solution heat-treated, stress relieved, then artificially aged. The stress relief is accomplished by stretching the metal by an amount that depends on the type of standard wrought product being made (extrusion or tube). The metal is not straightened after the stretching operation. This temper is closely related to T6511, which permits such straightening.
It has the lowest strength and lowest ductility compared to the other variants of 7049A aluminum.
The graph bars on the material properties cards below compare 7049A-T6510 aluminum to: 7000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
