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.

Abrasive for SiC


  • Features
  • Since silicon carbide (SiC) single crystal is receiving attention as a material for many power devices. However, it is extreamly hard and requires considerable skill and time to smoothen the surface down to the atom level.
    We have succeeded in developing an abrasive that can quickly smoothen silicon carbide to utilize our time-proven technology for developing abrasives.

New Zn materials for flexible batteries

  • Features
  • It is a zinc alloy foil(Electrolysis process) for batteries with discharge performance and suppression of gas generation Manganese batteries and zinc-air batteries can be processed into sheet type or winding type.
    It can be used as negative electrode material or additive for primary batteries and secondary batteries.

"New" Nb acid, Ta acid, Ti acid aqueous solution

"New" Nb acid, Ta acid, Ti acid aqueous solution

  • Features
  • It is an alkaline aqueous solution of Nb acid,Ta acid and Ta acid. Nb,Ta and Ti exist in an active state, and they have excellent film-forming properties, high reactivity, and uniform reactivity. For example, at room temperature and atmospheric pressure, it rapidly reacts with various metal ions to form polyacid salts.As a new material with functions not found in conventional oxide sols, it can be widely applied to coating agents, compounding precursors, etc.

"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.
