A413.0 (A413.0-F, S12A, A14130) Cast Aluminum
A413.0 aluminum is an aluminum alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. A413.0 is the Aluminum Association (AA) designation for this material. A14130 is the UNS number. Additionally, the SAE designation is 305. And the British Standard (BS) designation is LM6. Older literature may refer to this material as A13 or ASTM S12A.
The graph bars on the material properties cards below compare A413.0 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.
