713.0-T1 Cast Aluminum
713.0-T1 aluminum is 713.0 aluminum in the T1 temper. To achieve this temper, the metal is naturally aged until it meets standard mechanical property requirements. It has the lowest ductility compared to the other variants of 713.0 aluminum.
The graph bars on the material properties cards below compare 713.0-T1 aluminum to: ANSI/AA cast 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.
