What is YT5?
YT5 is a WC–TiC–Co cemented carbide containing 5 % TiC, an ISO P application-group grade supplied standard (STD), sinter-HIP (HIP) or coated. The cubic carbide addition raises hot hardness and crater-wear resistance when cutting steel, while the relatively high cobalt content keeps toughness for roughing and heavy interrupted cuts; usual forms are pressed inserts and brazed tool tips. The edge is usable to about 900 °C, but the grade is more brittle and much less thermally conductive than straight WC–Co, and it is not intended for cast iron or non-ferrous work. Use a YG grade there, or YT14 when wear resistance matters more than toughness. YT5 has a density of 13 g/cm³ (0.47 lb/in³), heavier than 86% of ceramic grades. It melts at 1,320°C (2,408 °F). The elastic modulus is 520 GPa (75.4 Msi).
What is YT5 used for?
- steel roughing
- general turning of carbon steel
- heavy interrupted cuts
Advantages
- Tough — resists crack growth — 11 MPa·√m (10 ksi·√in), better than 91% of ceramic grades
- Stiff — 520 GPa (75.4 Msi), better than 81% of ceramic grades
Limitations
- Needs corrosion protection — 40/100, worse than 96% of ceramic grades
- Heavy — 13 g/cm³ (0.47 lb/in³), worse than 86% of ceramic grades
- High embodied carbon — 25 kg CO₂/kg, worse than 78% of ceramic grades

Physical3
YT5 has a density of 13 g/cm³ (0.47 lb/in³), heavier than 86% of ceramic grades. It melts at 1,320°C (2,408 °F).
Mechanical9
The elastic modulus is 520 GPa (75.4 Msi).
Thermal5
YT5 is rated for continuous service to 900°C (1,652 °F). It conducts heat at 42 W/m·K (24.3 BTU/hr·ft·°F), better than 68% of ceramic grades. Thermal expansion is 6.2 µm/m·K (3.44 µin/in·°F).
Electrical1
YT5 has an electrical resistivity of 3.5×10⁻⁷ Ω·m.
Chemical & Environmental2
Corrosion resistance is fair (40/100), worse than 96% of ceramic grades.
Sustainability3
Producing a kilogram of YT5 takes about 350 MJ of energy and emits 25 kg of CO₂ — more than 81% of ceramic grades. Typical recycled content is 25%.
Manufacturability3
YT5's machinability is not recommended (5/100, worse than 59% of ceramic grades).

Working with YT5
Is YT5 easy to machine?
Sintered YT5 cannot be cut conventionally; shape it by diamond wheel grinding, EDM or laser only.
Can YT5 be welded?
Not welded. Brazed to steel tool bodies by vacuum or induction brazing with silver-copper (BAg-series) filler, with controlled cooling to prevent braze cracking.
Can YT5 be formed, bent or molded?
Powder pressed (die pressing or extrusion) then vacuum or low-pressure sintered, with about 18–20 % linear shrinkage; complex geometries rely on near-net-shape pressing.
YT5 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 |
|---|---|---|
| TiCtitanium carbide; raises crater wear resistance and red hardness | 4 – 6 | 5 |
| Cocobalt binder phase; controls toughness | 9 – 11 | 10 |
| WCtungsten carbide base with minor (W,Ti)C solid solution | balance |
What surface finishes work on YT5?
Diamond grinding followed by lapping and polishing gives mirror faces. Cutting tools are usually CVD or PVD coated with TiN, TiCN or Al2O3 to raise wear resistance.
