What is YG10 MG?

YG10 MG is YG10 in the MG grade — general-purpose balance of hardness and toughness for dies, punches, wear parts and cast-iron machining. YG10 MG 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). YG10 MG 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).

Chemical & Environmental2

Corrosion resistance is fair (40/100), worse than 96% of ceramic grades.

Corrosion ResistanceFair40/100
Chemical Resistance SummaryWC skeleton is very stable, but the cobalt binder is attacked by mineral and organic acids, chlorinated coolants and oxidising media; alkaline and neutral service is fine. Use Ni-binder or corrosion grades for wet acidic duty.

Sustainability4

Producing a kilogram of YG10 MG takes about 400 MJ of energy and emits 28 kg of CO₂ — more than 88% of ceramic grades. Typical recycled content is 30%.

Working with YG10 MG

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 MG — frequently asked

What is YG10 MG used for?

YG10 MG 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 MG?

YG10 MG 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 MG 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.

Can YG10 MG 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 MG?

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 MG 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 MG?

YG10 MG 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.
