EN AC-43500 (AlSi10MnMg) Cast Aluminum
EN AC-43500 aluminum is an aluminum alloy formulated for casting. 43500 is the EN numeric designation for this material. AlSi10MnMg is the EN chemical designation. It can have the highest ductility and has a moderately high electrical conductivity among Euronorm (EN) cast aluminums.
The properties of EN AC-43500 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 EN AC-43500 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.
