EN AC-43500-T7 Cast Aluminum
EN AC-43500-T7 is EN AC-43500 aluminum in the T7 temper. To achieve this temper, the metal is solution heat-treated and stabilized by artificial overaging. It has the lowest strength and highest ductility compared to the other variants of EN AC-43500 aluminum.
The graph bars on the material properties cards below compare EN AC-43500-T7 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.
