356.0-F Cast Aluminum
356.0-F aluminum is 356.0 aluminum in the as-fabricated (no temper or treatment) condition. It has the lowest strength compared to the other variants of 356.0 aluminum. The graph bars on the material properties cards below compare 356.0-F aluminum to: ANSI/AA 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.
