What is YG10 X?
YG10 X is YG10 heat treated to X — pick when both high hardness and edge strength are needed — micro drills, end mills, PCB tooling, precision punches. YG10 X has a tensile strength of 1,550 MPa (225 ksi), stronger than 101% of ceramic grades. Elongation at break is 0% and the elastic modulus is 580 GPa (84.1 Msi). YG10 X 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). MG is the default condition FabDigit quotes; X is available on request or by drawing note.

Working with YG10 X
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.
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.
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 |

YG10 X — frequently asked
What is YG10 X used for?
YG10 X 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 X?
YG10 X has a typical tensile strength of 1,550 MPa (225 ksi) — stronger than 101% of ceramic grades. Strength varies by condition: see the 3 listed tempers.
Is YG10 X easy to machine?
Not especially — machinability is rated not recommended (4/100, worse than 85% of ceramic grades). Only diamond grinding, lapping, wire/sinker EDM and laser; conventional cutting is impossible — near-net-shape press and sinter wherever possible.
Can YG10 X 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.
What surface finishes work on YG10 X?
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.
Can YG10 X 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.
What is the maximum service temperature of YG10 X?
YG10 X is rated for continuous use to about 550°C (1,022 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
