Cemented Carbide WC-Co K20 vs TiCN-based Cermet
Side-by-side chemical composition and mechanical property comparison.
Overview
Cemented Carbide WC-Co K20
ISO K20 cemented tungsten carbide with ~8% cobalt binder. The most widely used general-purpose WC-Co grade, balancing wear resistance and toughness. Hardness 91–92 HRA (~1450–1550 HV), density ~14.7 g/cm³, TRS 2200–2600 MPa. Medium grain. Applications: general turning, milling, drilling of cast iron, non-ferrous metals; end mills; wear parts with light impact; mining bits. ANSI C2, China YG8.
TiCN-based Cermet
Titanium carbonitride (TiCN) based cermet with Ni/Co binder. Lighter than WC-Co (density ~6.5–7.2 g/cm³), excellent surface finish capability, low coefficient of friction, high crater wear resistance, and good chemical stability at high temperatures. Hardness 91–93 HRA (~1500–1700 HV), TRS 1500–2000 MPa. Lower toughness than WC-Co. Applications: finish turning of steel and stainless steel, high-speed cutting, precision boring, grooving. Not suitable for heavy interrupted cuts.
