What is TiC CERMET-NiMo?
TiC CERMET-NiMo is TiC in the CERMET-NiMo condition — choose for tooling and dies where the Ni+Mo binder phase raises fracture toughness about threefold at a slight loss of hardness, with 60–80 % carbide giving 400 GPa modulus up to 900 °C. The elastic modulus is 400 GPa (58 Msi). TiC CERMET-NiMo has a density of 6 g/cm³ (0.217 lb/in³), heavier than 65% of ceramic grades. It melts at 3,067°C (5,553 °F). HP is the default condition FabDigit quotes; CERMET-NiMo is available on request or by drawing note.
Advantages
- Tough — resists crack growth — 9 MPa·√m (8.19 ksi·√in), better than 82% of ceramic grades

Working with TiC CERMET-NiMo
Is TiC easy to machine?
After sintering, only diamond wheel grinding or lapping is practical; because TiC is electrically conductive, wire and sinker EDM can be used for complex profiles.
Can TiC be welded?
Not fusion weldable; join to metals by active brazing with Ti/Zr-based fillers, or co-sinter with the Ni/Mo binder phase.
Can TiC be formed, bent or molded?
Powder metallurgy route: die pressing or isostatic pressing followed by vacuum or inert-atmosphere sintering at 1900–2200 °C, or hot pressing/SPS at 1800–2000 °C; Ni-Mo bonded cermet grades are liquid-phase sintered at about 1450 °C.
What surface finishes work on TiC?
Diamond lapping and polishing give a mirror finish; as a functional coating it is deposited by CVD at about 1000 °C or by PVD, where thermal expansion mismatch with the substrate can cause coating spallation.
TiC 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 |
|---|---|---|
| Cstoichiometric TiC = 20.05 wt% C; TiC_x (x=0.6-1.0) common | 19 – 20.1 | 19.9 |
| Free Cfree carbon, typical control value | ≤ 0.5 | 0.2 |
| Ooxygen content of the powder | ≤ 0.5 | 0.2 |

TiC CERMET-NiMo — frequently asked
What is TiC CERMET-NiMo used for?
TiC CERMET-NiMo is typically used for cermet cutting inserts, wear-resistant coatings, hardfacing additive and tiCN tool coatings. In short: lighter than WC carbides; cermet and coating carbide; EDM-machinable hard carbide.
Is TiC CERMET-NiMo easy to machine?
Not especially — machinability is rated not recommended (5/100, worse than 59% of ceramic grades). After sintering, only diamond wheel grinding or lapping is practical; because TiC is electrically conductive, wire and sinker EDM can be used for complex profiles.
Can TiC CERMET-NiMo be welded?

What is the maximum service temperature of TiC CERMET-NiMo?
TiC CERMET-NiMo is rated for continuous use to about 900°C (1,652 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
