EN AC-42000-F Cast Aluminum
EN AC-42000-F is EN AC-42000 aluminum in the as-fabricated (no temper or treatment) condition. It has the lowest strength and highest ductility compared to the other variants of EN AC-42000 aluminum. The graph bars on the material properties cards below compare EN AC-42000-F 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.
