Ti(C,N) powder 0.8-2µm for cermet cutting inserts. TiC0.5N0.5 to TiC0.7N0.3 and custom ratios, O < 0.6%, certified carbon/nitrogen per lot. Tungsten-free.
QUICK ANSWER
TiCN powder is titanium carbonitride — a TiC-TiN solid solution (typically TiC₀.₅N₀.₅ to TiC₀.₇N₀.₃) — whose tunable carbon-nitrogen ratio delivers hardness between TiC and TiN with better toughness and wettability than either. It is the modern standard hard phase in cermet cutting inserts and a premium additive in hardfacing and PVD-target manufacture.
The carbonitride advantage is metallurgical: nitrogen in the lattice refines the cermet microstructure, improves binder wetting during sintering, and raises toughness without sacrificing much hardness — which is why virtually all modern cermet grades are Ti(C,N)-based rather than straight TiC. The C:N ratio is a design dial: higher carbon for hardness and wear resistance, higher nitrogen for toughness and thermal shock resistance. Powder buyers specify the ratio, particle size (submicron for inserts), and oxygen content; lot-to-lot ratio consistency matters because it shifts sintering shrinkage and final grade properties.
MATERIAL DATA
Lot-level controls focus on the chemistry, particle characteristics, and process values that influence manufacturing consistency and finished-part performance.
| Element | Content | Performance Role |
|---|---|---|
| Titanium (Ti) | ~78-82 wt% | Metallic base of the carbonitride lattice |
| Combined carbon (C) | 8-14 wt% (ratio dependent) | Carbon fraction — the hardness dial |
| Nitrogen (N) | 8-14 wt% (ratio dependent) | Nitrogen fraction — the toughness and wetting dial |
| Oxygen (O) | < 0.6 wt% (submicron grades) | Surface oxide hinders binder wetting in sintering |
| Free carbon | < 0.3 wt% | Controlled to prevent brittle phase formation |
Final limits can be aligned with the agreed purchase specification.
APPLICATIONS
Cermet cutting insert manufacture is the dominant application: modern cermet grades use Ti(C,N) as the core hard phase with WC, Mo₂C, TaC/NbC additions in Ni-Co binder, sintered into finishing inserts that dominate steel finishing in automotive transmission and bearing production. The insert maker's grade development starts from the carbonitride ratio and particle size — fine, consistent TiCN powder with certified C:N ratio is the foundation raw material, purchased on long qualification cycles and then in steady volume.
Beyond inserts, TiCN serves PVD coating target production (sintered TiCN targets deposit the blue-black wear coatings on drills and end mills), hardfacing blends where its toughness outperforms TiC in impact-loaded wear, and cermet rod and wear part production for seal rings and nozzles. Each market rewards the same powder attributes: ratio consistency, submicron size with narrow distribution, and low oxygen.
