Aluminium AlSi10Mg

Product Information

AlSi10Mg is a typical casting alloy with good casting properties and is used for cast parts with thin walls and complex geometry. The alloying elements silicon and magnesium lead to high strength and hardness. The alloy also features good dynamic properties and is therefore used for parts subject to high loads. Parts in EOS Aluminium AlSi10Mg are ideal for applications which require a combination of good thermal properties and low weight, e.g. for motor sport.

Properties:

  • Direct manufacture of functional prototypes
  • Small production runs
  • User-specific products or spare parts
  • Automotive
  • Engineering
  • Motor racing
  • Aerospace
  • Pneumatics
  • Prototype parts for aluminium die casting
