EN AC-45100-T4 Cast Aluminum
EN AC-45100-T4 is EN AC-45100 aluminum in the T4 temper. To achieve this temper, the metal is solution heat-treated and naturally aged. The graph bars on the material properties cards below compare EN AC-45100-T4 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.
