Aluminum 3D Printing

3D-printed aluminum offers high temperature and corrosion resistance and an excellent strength-to-weight ratio

Aluminum (AlSi10Mg) is comparable to a 3000 series alloy that is used in casting and die casting processes. It has good strength -to-weight ratio, high temperature and corrosion resistance, and good fatigue, creep and rupture strength. AlSi10Mg also exhibits thermal and electrical conductivity properties. Final parts built in AlSi10Mg receive stress relief application.

Primary Benefits

  • High stiffness and strength relative to weight
  • Thermal and electrical conductivity
  • High temperature and corrosion resistance
