Specification Designations Hardmetals Cemented Carbides

Engineering Materials

Cemented Carbides coinsists of particles that are hard, brittle, nonmetallic refractory material, typically carbides but sometimes carbonitrides or nitrides, in a metallic binder (matrix) phase, typically cobalt but sometimes nickel, iron, or their alloys.
