AlSi10Mg Aluminium alloy

A widely used alloy that combines low weight
and good mechanical properties.

Key features

This aluminum alloy, which belongs to a narrower group of silumins, is characterized mainly by high thermal and electrical conductivity, low density, high corrosion resistance and good mechanical properties, and its properties can be greatly influenced
by the heat treatment of this material.

Suitable uses

A good ratio between mechanical properties and density make AlSi10Mg a suitable choice for a large number of engineering applications in aerospace and automotive. Due to its high thermal conductivity, it is used, for example, for the production of heat sinks and heat exchangers. This material is also a suitable alternative for the rapid production of aluminum castings.

Specific applications

  • topologically optimized bracket for aerospace industry
  • heat exchanger for energy industry
  • prototype of electric motor chassis with cooling
