EN AC-43200 (AISi10Mg(Cu)) Cast Aluminum
EN AC-43200 aluminum is an aluminum alloy formulated for casting. 43200 is the EN numeric designation for this material. AISi10Mg(Cu) is the EN chemical designation.
The properties of EN AC-43200 aluminum include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN AC-43200 aluminum to: Euronorm (EN) 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 EN AC-43200 aluminum is notable for including lead (Pb) and containing a comparatively high amount of silicon (Si). Lead is used to improve machinability at the cost of toxicity and a decrease in weldability. Silicon is used to improve casting fluidity and lower melting temperature. It also has a strengthening effect.
