YW1
ISO M10
YW1 is a WC-TiC-TaC(NbC)-Co universal cemented carbide in which tantalum and niobium carbide additions balance hardness against toughness, so one grade covers steel as well as cast iron and heat-resistant alloys.

What is YW1?
YW1 is a WC-TiC-TaC(NbC)-Co universal cemented carbide in which tantalum and niobium carbide additions balance hardness against toughness, so one grade covers steel as well as cast iron and heat-resistant alloys. It is used for stainless steel and superalloy cutting and general finishing, supplied as sintered inserts, brazed tips and blanks in STD, fine-grain (FG) and coated conditions. Density is 12.9 g/cm3, elastic modulus 520 GPa, thermal conductivity 30 W/m·K and service temperature about 900 °C. It is not as hard as YT30 in pure steel finishing, and the cobalt binder limits chemical resistance; use YW2 for heavier, more interrupted cuts. YW1 has a density of 12.9 g/cm³ (0.466 lb/in³), heavier than 84% of ceramic grades. It melts at 1,320°C (2,408 °F). YW1 has a tensile strength of 850 MPa (123 ksi), stronger than 81% of ceramic grades. Elongation at break is 0% and the elastic modulus is 520 GPa (75.4 Msi).

Working with YW1
Is YW1 easy to machine?
Only diamond-wheel grinding, diamond lapping, wire/sinker EDM or laser — no conventional cutting; grind wet to avoid thermal cracks.
Can YW1 be welded?
Not fusion weldable; join by silver/copper brazing (Ag-Cu-Ti or AgCuZn at 700–900 °C) with a ductile shim to absorb CTE mismatch, or by shrink fit.
Can YW1 be formed, bent or molded?
Shaped by uniaxial/CIP powder pressing, extrusion or injection moulding of the WC-TiC-TaC-Co powder followed by liquid-phase sinter-HIP; ~18–22 % linear shrinkage must be allowed for.
YW1 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Cobinder phase | 5 – 7 | 6 |
| TiCcubic carbide, crater-wear resistance | 4 – 7 | 5.5 |
| TaC+NbCgrain-growth inhibition, hot strength | 2.5 – 5 | 4 |
| WCbalance, ~84–85 % | balance |
What surface finishes work on YW1?
Diamond lap or polish to Ra <0.1 µm before CVD/PVD coating; edge honing controls chipping, and passivation/dry storage protects the cobalt binder.

YW1 — frequently asked
What is YW1 used for?
YW1 is typically used for stainless steel machining, heat-resistant alloy cutting and general-purpose finishing. In short: universal steel and cast-iron grade; balanced hardness and toughness; highest thermal conductivity in group.
What is the tensile strength of YW1?
YW1 has a typical tensile strength of 850 MPa (123 ksi) — stronger than 81% of ceramic grades.
Is YW1 easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 59% of ceramic grades). Only diamond-wheel grinding, diamond lapping, wire/sinker EDM or laser — no conventional cutting; grind wet to avoid thermal cracks.
