Density as a function of the Co content. (WC-Co carbides only)
Density is determined according to the standard EN 23 369 (ISO 3369). The wide variation in the density of the constituents of Cemented Carbide (i.e. WC=15.7 g/cm3, Co=8.9 g/cm3, TaC 13.2 g/cm3 and TiC=4.9 g/cm3) result in large variations in the density of Cemented Carbides in line with their composition.
Typically, the density of Cemented Carbides can be 50-100% greater than that of the steel. This is an important consideration when weight is a major factor in component design.
