360.0 (360.0-F, SG100B, A03600) Cast Aluminum

360.0 aluminum is an aluminum alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. 360.0 is the Aluminum Association (AA) designation for this material. A03600 is the UNS number. Older literature may refer to this material as ASTM SG100B, but this is now discouraged.

The graph bars on the material properties cards below compare 360.0 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 360.0 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.

Aluminum (Al) 85.1 to 90.6
Silicon (Si) 9.0 to 10
Iron (Fe) 0 to 2.0
Magnesium (Mg) 0.4 to 0.6
Copper (Cu) 0 to 0.6
Nickel (Ni) 0 to 0.5
Zinc (Zn) 0 to 0.5
Manganese (Mn) 0 to 0.35
Tin (Sn) 0 to 0.15
Residuals 0 to 0.25
