Side-by-side chemical composition and mechanical property comparison.
Overview
Cemented Carbide WC-Co K10
ISO K10 cemented tungsten carbide with ~6% cobalt binder. The hardest standard WC-Co grade (92–93 HRA, ~1600 HV) with highest wear resistance but lowest toughness. Density ~14.9 g/cm³, TRS 1800–2200 MPa, elastic modulus ~620 GPa. Fine to submicron grain. Applications: finish turning and boring of cast iron, non-ferrous metals, hardened steel; PCB drilling; wire drawing dies; seal rings; wear parts with no impact. ANSI C2/C3, China YG6.
Cemented Carbide WC-TiC-TaC-Co M20
ISO M20 multi-purpose cemented carbide with WC + TiC + TaC + Co. Bridges the gap between K (cast iron) and P (steel) grades. Moderate crater wear resistance from TiC/TaC with better toughness than pure P-grades. Hardness 90–91 HRA, density ~13.0–14.0 g/cm³, TRS 2000–2400 MPa. Applications: stainless steel (austenitic), heat-resistant alloys, ductile cast iron, mixed production. ANSI C7, China YW2.
