EOS Aluminum AlSi10Mg is a widely used alloy that combines lightweight and good mechanical properties. Different treatments may be applied to modify aluminum’s properties, including increasing ductility and conductivity. Aluminum has good thermal and electrical conductivity, especially after it has been treated. Projects requiring parts that are gas-tight can be produced using EOS Aluminum AlSi10Mg. This method is often used to cast parts with thin walls and complex geometry because it has good casting properties. Aluminum has good strength, hardness, and dynamic properties that make it useful for parts subject to high loads.
Parts in EOS Aluminum AlSi10Mg are ideal for applications that 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.
Conventionally cast components in this type of aluminum alloy are often heat-treated to improve the mechanical properties, for example, using the T6 cycle of solution annealing, quenching and age hardening.
The laser-sintering process is characterized by extremely rapid melting and re-solidification. This produces metallurgy and related mechanical properties in the as-built condition, which is similar to T6 heat-treated cast parts. Therefore, such hardening heat treatments are not recommended for laser-sintered parts, but rather a stress-relieving cycle of 2 hours at 300 °C (572 °F). Due to the layerwise building method, the parts have a certain anisotropy, which can be reduced or removed by appropriate heat treatment – see Technical Data for examples.
