A360.0 (SG100A, A13600) Cast Aluminum
A360.0 aluminum is an aluminum alloy formulated for casting. A360.0 is the Aluminum Association (AA) designation for this material. A13600 is the UNS number. Additionally, the SAE designation is 309. The British Standard (BS) designation is LM9. And the AFNOR (French) designation is A-S10G. Older literature may refer to this material as ASTM SG100A, but this is now discouraged.
The properties of A360.0 aluminum include three common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare A360.0 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.

Alloy Composition
Among cast aluminum alloys, the composition of A360.0 aluminum is notable for containing a comparatively high amount of silicon (Si) and including tin (Sn). Silicon is used to improve casting fluidity and lower melting temperature. It also has a strengthening effect. Tin is used to increase bearing properties at the cost of a decrease in corrosion resistance.
