Dark gray light powder. Fully carburized and dense alloyed powder. Compared with normal WC powder by traditional process, it has more uniform structure and higher thermal stability and much bigger and coarser grain.
Applications:
It is a new kind of cemented carbide material which can be used as substrate material for oil drilling and geological prospecting tools , thermal spraying material.
Particle size range:
0.84mm-0.038mm
