What is TiN PS?
TiN PS is TiN heat treated to PS — lower-cost route for larger or complex bulk shapes where some residual porosity and lower hardness are acceptable. The elastic modulus is 210 GPa (30.5 Msi). TiN PS has a density of 5 g/cm³ (0.181 lb/in³), heavier than 51% of ceramic grades. It melts at 2,950°C (5,342 °F). HP is the default condition FabDigit quotes; PS is available on request or by drawing note.

Physical3
TiN PS has a density of 5 g/cm³ (0.181 lb/in³), heavier than 51% of ceramic grades. It melts at 2,950°C (5,342 °F).
Mechanical9
The elastic modulus is 210 GPa (30.5 Msi).
Thermal5
TiN PS is rated for continuous service to 550°C (1,022 °F). It conducts heat at 22 W/m·K (12.7 BTU/hr·ft·°F), better than 51% of ceramic grades. Thermal expansion is 9.4 µm/m·K (5.22 µin/in·°F).
Electrical2
TiN PS has an electrical resistivity of 6×10⁻⁷ Ω·m.
Chemical & Environmental2
Corrosion resistance is very good (75/100), better than 50% of ceramic grades.
Sustainability3
Producing a kilogram of TiN PS takes about 200 MJ of energy and emits 15 kg of CO₂ — more than 63% of ceramic grades. Typical recycled content is 0%.
Manufacturability3
TiN PS's machinability is not recommended (10/100, better than 76% of ceramic grades).

Working with TiN PS
Is TiN easy to machine?
Bulk TiN is machined only by diamond grinding, lapping or laser; because it is electrically conductive it can also be wire/sink EDM'd — a key advantage over insulating nitrides.
Can TiN be welded?
Not weldable; joined by active-metal brazing (Ti/Zr-containing filler), diffusion bonding or mechanical clamping.
Can TiN be formed, bent or molded?
Shaped by uniaxial/CIP pressing then hot-pressing or SPS at 1650–2000 °C (pressureless sintering needs Ni/Co aid); coatings are produced by cathodic-arc/sputter PVD at 200–500 °C or CVD at 900–1050 °C in N₂/TiCl₄.
What surface finishes work on TiN?
Substrate must be polished before coating — PVD TiN replicates the surface; gold film can be polished, passivated or over-coated (TiCN/TiAlN) and is stripped chemically in H₂O₂-based baths for recoating.
TiN 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 |
|---|---|---|
| N | 21 – 23 | 22.6 |
| Osurface oxide on powder | ≤ 1 | 0.4 |
| Cfrom carbothermal route | ≤ 0.5 | 0.15 |
| Nionly in liquid-phase (pressureless) sintered grades | ≤ 3 | — |
| Tistoichiometric TiN₁.₀; commercial TiNx ranges x ≈ 0.6–1.1 | ≥ 76 (balance) | — |
TiN PS — frequently asked
What is TiN PS used for?
TiN PS is typically used for cutting tool PVD coatings, wear-resistant coatings, decorative gold-tone finishes, diffusion barrier layers and medical implant coatings. In short: conductive, EDM-able nitride; standard gold tool coating; 600 °C oxidation limit.
Is TiN PS easy to machine?
Not especially — machinability is rated not recommended (10/100, better than 76% of ceramic grades). Bulk TiN is machined only by diamond grinding, lapping or laser; because it is electrically conductive it can also be wire/sink EDM'd — a key advantage over insulating nitrides.

What is the maximum service temperature of TiN PS?
TiN PS 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.
