6013-T651 Aluminum

6013-T651 aluminum is 6013 aluminum in the T651 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 (sheet, plate, bar, or forging).

It has the lowest ductility compared to the other variants of 6013 aluminum.

The graph bars on the material properties cards below compare 6013-T651 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.
