# A535.0 (A535.0-F, A15350) Cast Aluminum

A535.0 aluminum is an aluminum alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. A535.0 is the Aluminum Association (AA) designation for this material. A15350 is the UNS number.

The graph bars on the material properties cards below compare A535.0 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 A535.0 aluminum is notable for containing a comparatively high amount of magnesium (Mg). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion.
