When to choose which
Choose TiAlN PVD
Choose TiAlN PVD when higher hot hardness is required.
- About 3300 HV hardness
- Useful to about 800 °C
- Strong hot-wear performance
Choose TiN PVD
TiN PVD is the pick when its strengths below matter more than TiAlN PVD's.
- About 2300 HV surface hardness
- Recognizable gold decorative colour
- 1–5 µm film preserves sharp edges
What the numbers say
- TiAlN PVD resists corrosion better.
- TiN PVD is the lower-cost option ($$$$).
- TiAlN PVD is semi-conductive; TiN PVD is conductive.
- TiAlN PVD tolerates more heat (800 °C continuous).
Scores side by side
Each score is 0–100 against every finish in this catalog. Corrosion is derived from salt-spray test duration and surface hardness from the finish layer's Vickers hardness where a measured figure exists; a finish that leaves the base metal's own surface is not rated for hardness. Cosmetic, lubricity and cost are FabDigit's engineering assessment. Scores and typical figures are screening data, not matched side-by-side tests or service-life rankings; ASTM B117 is a controlled salt-fog method, not a field-life prediction.
