EN AC-46400-F Cast Aluminum

EN AC-46400-F is EN AC-46400 aluminum in the as-fabricated (no temper or treatment) condition. The graph bars on the material properties cards below compare EN AC-46400-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.
