Metal and Compound Powders

Under DevelopmentMetal Powders for Additive Manufacturing

JX Nippon Mining & Metals Group companies are developing and manufacturing metal powders of various kinds for additive manufacturing.

JX Nippon Mining & Metals Corporation: Copper Powder (under development)

Applying our proprietary surface treatment technology to high-quality copper powder, we are developing copper powder applicable to various methods of metal additive manufacturing.

Benefits of Surface Treatment

  • Anti-oxidation effect: Surface treatment prevents an increase in oxygen content, which inhibits AM processing.
  • Powder sintering inhibition effect: In Electron-Beam (EB) AM, surface treatment inhibits powder sintering during the preheating process, for more flexible AM processing.
  • Improvement of laser absorption ratio: Formation by Laser Beam (LB) AM is considered to be difficult with ordinary copper powders, but improving the laser absorption ratio increases the potential for its use.

Powder sintering inhibition effect (Electron Beam AM)

How objects are formed
  • Through preheating process of electron-beam AM, redundant powders can bond with each other excessively by heat, resulting in difficulty in removing the powders.
