EOS CopperAlloy CuCrZr DMSL on EOS M 400; 80 µm Layer Thickness
Categories: Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Copper Alloy

Material Notes: Copper alloy CuCrZr has a favorable combination of electrical and thermal conductivity accompanied with good mechanical properties. This alloy reaches its good properties during heat treatment.

Main Characteristics:

  • High productivity 12 mm3/s with 80 µm layer thickness
  • Moderate to high conductivity in heat treated condition together with good mechanical properties
  • Chemical composition corresponds to C18150 and CW106C
Typical Applications:
  • Rocket engine parts
  • Heat exchangers
  • Induction coils
heat-treatment: 1. Hold 30 min at ~ 980 °C in argon atmosphere, water cooling to room temperature. 2. Hold 3 h at ~ 430 °C in argon atmosphere, slow cooling in argon by taking the samples out of the furnace and rest in air.
