What is YG10?
YG10 is a straight WC–Co cemented carbide with a nominal 10 % cobalt binder and no cubic carbide additions, supplied in MG, X and C conditions. The higher binder content buys toughness for heavy wear and impact duty such as cold forming dies, rock drilling inserts and wear nozzles, with an elastic modulus near 570 GPa and thermal conductivity of 85 W/m·K. Service temperature is limited to about 550 °C and corrosion resistance is modest (score 40) because acids attack the cobalt phase. Sintered parts can only be diamond ground or EDM'd, so press-and-sinter near-net shapes control cost; YG8 is harder and less tough, YG15 tougher still. YG10 has a density of 14.5 g/cm³ (0.524 lb/in³), heavier than 91% of ceramic grades. It melts at 1,320°C (2,408 °F). YG10 has a tensile strength of 1,300 MPa (189 ksi), stronger than 97% of ceramic grades. Elongation at break is 0% and the elastic modulus is 570 GPa (82.7 Msi).

Working with YG10
Is YG10 easy to machine?
Only diamond grinding, lapping, wire/sinker EDM and laser; conventional cutting is impossible — near-net-shape press and sinter wherever possible.
Can YG10 be welded?
Not fusion weldable; join by vacuum/induction brazing with Ag-Cu-Ni filler below 900 °C or by shrink/press fit into steel bodies.
Can YG10 be formed, bent or molded?
Shaped by uniaxial pressing, CIP, extrusion or injection moulding of WC-Co powder, then vacuum sinter-HIP at ~1420 °C with ~18–22 % linear shrinkage.
YG10 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 |
|---|---|---|
| Cometallic binder phase | 9 – 11 | 10 |
| Ccombined carbon in WC; free C and eta phase not permitted | 5.4 – 5.7 | 5.55 |
| TaC+NbCoptional grain-growth inhibitor in some producer variants | 0 – 0.5 | 0.2 |

What surface finishes work on YG10?
Diamond lapping to mirror finish; PVD TiN/TiAlN or CVD coatings common; can be micro-blasted or electropolished-free — no plating needed for wear duty.
How much does YG10 cost?
YG10 is a high-cost ceramic ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
YG10 — frequently asked
What is YG10 used for?
YG10 is typically used for cold forming dies, wear-resistant nozzles, rock drilling and structural wear parts. In short: tougher than YG8; general heavy-wear WC-Co; high binder, high toughness.
What is the tensile strength of YG10?
YG10 has a typical tensile strength of 1,300 MPa (189 ksi) — stronger than 97% of ceramic grades. Strength varies by condition: see the 3 listed tempers.
Is YG10 easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 59% of ceramic grades). Only diamond grinding, lapping, wire/sinker EDM and laser; conventional cutting is impossible — near-net-shape press and sinter wherever possible.
