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.
