+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.
