About Our Additive Manufacturing Business and Products

High-quality Copper Powder with Our Novel Surface Treatment

The surface treatment adds an anti-oxidization effect and prevents an increase in the oxygen content, which inhibits AM processing.

For electron-beam AM, the surface treatment exhibits the powder sintering inhibition effect during the preheating process. Such an effect allows us to increase flexibility of AM processing. Laser absorption ratio is increased because of the surface treatment enabling the manufacture of the pure copper object through laser beam AM.
