Density as a function of the cobalt content (WC-Co carbides only)

Density is determined according to the standard EN 23 369 (ISO 3369). The wide variation in the densities 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) results in large variations in the density of cemented carbides in line with their composition.

Typically, the density of cemented carbides can be 50 to 100% greater than that of the steel. This is an important consideration when weight is a major factor in component design. Hyperion Materials & Technologies can develop cemented carbides with densities that solve your application needs.
