AlTiN — the coating that thrives on heat.
Outstanding oxidation resistance in the hardest conditions — dry milling, high-speed, and hardened steel.
What AlTiN is, in numbers.
Approximate properties — final spec is confirmed for every job during quote.
Boost tool life and speeds with AlTiN PVD: dry machining, 900 °C heat resistance, extreme wear protection.
Made for the temperatures TiN can't handle.
AlTiN keeps its hardness at temperatures that would degrade TiN, because the aluminum in the film oxidizes into a thin alumina layer right at the cutting edge. That alumina layer is a passive barrier: it protects the coating and the substrate underneath from further oxidation, and it dramatically extends life on dry and high-speed cutting.
If you're running dry or near-dry, machining hardened steel above 45 HRC, or seeing thermal wear on your cutting tools, AlTiN is our first recommendation. It also handles the intermittent heat of high-feed operations better than TiN or TiCN.
For lower-temperature abrasive wear (injection molds, forming dies), consider TiCN or CrN instead.
Where AlTiN wins
- High-temperature millingKeeps hardness where TiN breaks down.
- Dry & near-dry cuttingAlumina layer resists edge oxidation.
- Hardened steel machiningReliable on tool steels above 45 HRC.
