6101B-T7 Aluminum

6101B-T7 aluminum is 6101B aluminum in the T7 temper. To achieve this temper, the metal is solution heat-treated and stabilized by artificial overaging. The graph bars on the material properties cards below compare 6101B-T7 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.
