8090-T3 Aluminum
8090-T3 aluminum is 8090 aluminum in the T3 temper. To achieve this temper, the metal is solution heat-treated, strain hardened, then naturally aged. It has the lowest strength and highest ductility compared to the other variants of 8090 aluminum.
The graph bars on the material properties cards below compare 8090-T3 aluminum to: otherwise unclassified aluminums (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.
