6105-T1 Aluminum
6105-T1 aluminum is 6105 aluminum in the T1 temper. To achieve this temper, the metal is naturally aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare 6105-T1 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.
