EN AC-43500-T5 Cast Aluminum

EN AC-43500-T5 is EN AC-43500 aluminum in the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. It has the highest strength and lowest ductility compared to the other variants of EN AC-43500 aluminum.

The graph bars on the material properties cards below compare EN AC-43500-T5 to: Euronorm (EN) 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.
