EN AC-43100-T64 Cast Aluminum

EN AC-43100-T64 is EN AC-43100 aluminum in the T64 temper. To achieve this temper, the metal is solution heat-treated and artificially underaged. The degree of underaging is different from T61 and T65.

The graph bars on the material properties cards below compare EN AC-43100-T64 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.
