6101-T64 Aluminum
6101-T64 aluminum is 6101 aluminum in the T64 temper. To achieve this temper, the metal is solution heat-treated and artificially underaged. The degree of underaging is different from T61 and T65. The graph bars on the material properties cards below compare 6101-T64 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.
