What is the difference between cemented and tungsten carbide?
Cemented carbides consist of hard grains of the carbides of transition metals (Ti, V, Cr, Zr, Mo, Nb, Hf, Ta, and/or W) cemented or bound together by a softer metallic binder consisting of Co, Ni, and/or Fe (or alloys of these metals). Tungsten carbide (WC), on the other hand, is a compound of W and C. Since most of the commercially important cemented carbides are based on WC as the hard phase, the terms “cemented carbide” and “tungsten carbide” are often used interchangeably.
