Copper Powder for 3D Printing

  • Copper is challenging to be fully densified via additive manufacturing due to its high reflectivity of IR laser and high thermal conductivity. We have the two copper alloy grades for L-PBF (laser powder bed fusion) with great performance of 3D printed parts by achieving full densification with the IR laser output of 400W. We have the standard parameters for both and can share them with you based on NDA, which can reduce development cost on your side.
  • Features
    electrical conductivity of 95%IACS and thermal conductivity of 377W/mK

    Applications
    thermal management applications including heat sink and cold plate, induction coil, rocket chamber and high electrical applications for EVs: motor, connector and bus bar

High Conductivity Grade:MA-CCR25L

  • Features
    high tensile strength:755MPa, comparable to copper beryllium with conventional process

    Applications
    tooling, tip for welding and inlet guide vanes

High Strength Grade MA-CCR25H

  • We have high quality copper powders for not only L-PBF, but also other 3D printing processes such as DED (Directed Energy Deposition), binder jetting, DLP (Digital Light Processing) and cold spray.

"New" Dendritic Silver Powder

  • Features
  • We succeeded in producing silver powder with low apparent density by our original technique to produce dendritic shape powder.
    It is possible to reduce the cost, because good conductivity can be obtained with less amount than conventional silver powder.
    It can be used for conductive stretchable materials.
