Copper 3D Printing
3D-printed copper provides strong mechanical properties with high thermal and electrical conductivity
Copper (CuNi2SiCr) is an alloyed copper material with excellent thermal and electrical conductivity. This alloy can be used in harsh environments where pure copper is not feasible. Copper is structurally stronger, harder, and has higher elongation when compared to AlSi10Mg, which also exhibits thermal and electrical conductivity properties. Final parts built in CuNi2SiCr receive stress relief application.
Primary Benefits
- Good thermal and electrical conductivity
- Better corrosion resistance than pure copper
- Robust mechanical properties
