Refractory Group Metals are a class of metals that are extraordinarily resistant to heat and wear. 

High melting points make powder metallurgy the method of choice for fabricating components from these metals.

Mill Processed Powder
RF Plasma Powder  

RF Plasma produces dense spherical powders ideal for Particle Injection Molding and Additive Manufacturing technologies 

Spherical powders processed by RF Plasma display high flow-ability and a superior Tap Density in these applications

RF Plasma is a "Refractory Free" process where the potential of inclusions from ceramic melt crucibles is eliminated

The Low Turbulence process forms a dense spherical morphology superior to inert gas atomization technologies
