ADDITIVA\_Aluminium AlSi10Mg\_rev010.docx 9  
Aluminium AlSi10Mg is a common casting alloy with good castability. It is typically used for thin \- walled, complex  
components and applications requiring a combination of good thermal properties and low weight. It offers excellent  
strength, hardness, and dyn amic performance, making it suitable for parts subjected to high loads. Traditionally, cast  
parts made from this aluminium alloy are heat \- treated to enhance mechanical properties, typically via the T6 cycle of  
solution annealing, quenching, and age hardeni ng.  
The SLM/DMLS process is notable for its extremely rapid melting and re \- solidification, allowing mechanical properties  
in the as \- built condition to be comparable to those of T6 heat \- treated cast parts. Thanks to its high strength \- to \- weight  
ratio, AlSi10Mg i s an excellent choice for automotive and aerospace applications, especially gearboxes, housings, and  
brackets that endure significant loading. Components can be machined, spark \- eroded, welded, shot \- peened, polished,  
and coated.
