Cemented Carbide WC-Co K10 vs Cemented Carbide WC-TiC-Co P20
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-Co P20
ISO P20 cemented carbide with WC + TiC/TaC + Co. Designed for machining steel and steel castings. TiC addition provides crater wear resistance essential for steel cutting. Hardness 91–92 HRA, density ~12.0–13.0 g/cm³ (lower than K-grades due to TiC), TRS 1800–2200 MPa. Applications: general turning, milling, planing of carbon steel, alloy steel, tool steel, ferritic and martensitic stainless steel. ANSI C6, China YT15.
