6360-T66 Aluminum
6360-T66 aluminum is 6360 aluminum in the T66 temper. To achieve this temper, the metal is solution heat-treated and artificially aged, with additional process control to yield more favourable properties. It has the highest strength compared to the other variants of 6360 aluminum.
The graph bars on the material properties cards below compare 6360-T66 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.
