EN AC-48100-T5 Cast Aluminum

EN AC-48100-T5 is EN AC-48100 aluminum in the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare EN AC-48100-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.
