# 513.0 (513.0-F, formerly A514.0, GZ42A, A05130) Cast Aluminum

513.0 aluminum is an aluminum alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. 513.0 is the Aluminum Association (AA) designation for this material. A05130 is the UNS number. Older literature may refer to this material as A514.0 or ASTM GZ42A.

The graph bars on the material properties cards below compare 513.0 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 513.0 aluminum is notable for containing comparatively high amounts of magnesium (Mg) and zinc (Zn). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion. Zinc is used to achieve significant increases in strength, at the cost of increased susceptibility to stress corrosion cracking. Among other things, this limits weldability.
