6162-T6511 Aluminum
6162-T6511 aluminum is 6162 aluminum in the T6511 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 straightened after the stretching operation. This temper is closely related to T6510, which does not permit such straightening.
The graph bars on the material properties cards below compare 6162-T6511 aluminum to: 6000-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.
