EN AC-42100 (AISi7Mg0.3) cast aluminum
EN AC-42100 aluminium is an aluminium alloy formulated for casting. 42100 is the EN numeric name for this material. In addition, the chemical name of EN is AISi7Mg0, 3.
It has the highest electrical conductivity of European standard (EN) cast aluminium. In addition, it has a moderately high melting temperature and moderately high thermal conductivity.
The properties of EN AC-42100 aluminum include two common variations. This page shows a summary range for both. For more specific values, click on the link below. The chart bar on the Material Properties card below compares EN AC-42100 aluminum to: European Standard (EN) cast aluminum (top), all aluminum alloys (middle) and the entire database (bottom). The full bar line means that this is the maximum in the relevant set. A half-full bar means it's 50% of the top price, and so on.
