Aluminum (AlSi10Mg)

Aluminium AlSi10Mg

General applications

Aluminium AlSi10Mg is a traditional metal alloy used in castings with low density and good thermal properties. Due to its density and easy manufacturability, it is one of the cheapest 3D printable metal materials.

Parts made of aluminium have good mechanical properties and it is an ideal material for applications where thermal conductivity and lightness are required. Typical applications are fully functional end products and spare parts.

Aluminium AlSi10Mg is well suited for serial production, and pieces and parts made from it can be used in many different fields. Due to its lightness and good thermal properties, aluminium AlSi10Mg is particularly suitable for the needs of the automotive and aviation industries.

Examples of fields and areas of use:

  • Auto industry
  • Aviation industry
  • Industrial components
  • Industrial spare parts
  • Jigs and other tools
  • Electronics industry

Using the material in industrial 3D printing

With good planning and optimization, considerable savings can be achieved with 3D printed aluminium parts compared to cast and machined parts.

Aluminium AlSi10Mg is one of the easiest printing materials. It conducts heat very well, which means there are fewer printing restrictions. Support structures are not needed as much as, for example, in steel. In terms of finishing, the material is also easier to handle.

Aluminium AlSi10Mg has to be heat treated to improve its mechanical properties. Without heat treatment, the elongation at break is extremely low, and the hardness is high. Typical heat treatment is done by warming the piece at 300 degrees for 2 hours, which gives the piece good and stable mechanical properties. Heat treatments can be done as needed, for example T6 treatment is one option.
