DMLS ALUMINIUM AlSi10Mg AlSi10Mg is a typical casting alloy with good properties and is typically used for parts with thin walls and complex geometry. It oﬀers good strength, hardness and dynamic properties and is therefore also used for parts subject to high loads. Parts in Aluminium AlSi10Mg are ideal for applications which require a combination of good thermal properties and low weight. They can be machined, spark-eroded, welded, micro shot-peened, polished and coated if required.
