6082-T6 Aluminum

6082-T6 aluminum is 6082 aluminum in the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. It has the second highest strength compared to the other variants of 6082 aluminum.

The graph bars on the material properties cards below compare 6082-T6 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.
