EN AC-43200-T6 Cast Aluminum
EN AC-43200-T6 is EN AC-43200 aluminum in the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare EN AC-43200-T6 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.
