Aluminium

Aluminium Al-Si10Mg

It is an aluminium alloy including silicon as well as trace amounts of magnesium and iron. It’s an aluminium alloy with silicon and trace amounts of magnesium and iron. The material has good corrosion resistance due to the spontaneous production of an oxide layer on the surface of the aluminium alloy, which can be further strengthened by chemically anodizing.

  • Key features: Good thermal conductivity • Electrical conductivity • Low density.
  • Applications: It is primarily used in motorsports and 3D printing functional prototypes. It is also suitable for series-production parts.
  • See the datasheet
