Cemented tungsten carbide (WC-Co) is a powder-metallurgy composite of tungsten carbide grains in a cobalt binder. The standard material for granulator, shear and high-abrasion industrial blades.

YG6X and YG8 are the two most-specified Chinese GB standard tungsten carbide grades for industrial knives. The 2 % cobalt difference looks small but it changes the wear-toughness trade, the impact resistance, and the substrate fit. Here is the engineering comparison.
