Aluminum Titanium Nitride (AlTiN)
The design of our AlTiN coating provides exceptional oxidation resistance and extreme hardness. This coating works well in very demanding cutting tool applications, especially when tools are being pushed to the max.
- Thickness: .0001″ – .0002″ (2 – 5 microns)
- Hardness: 4000 – 4200 Hv
- Oxidation Resistant (up to 800 – 900°C)
- Deposition Temp. 700° – 800°F
- Provides 2 – 7 x the tool life vs. uncoated tools.
- Good wear & oxidation resistance
- Biocompatible, used on many medical instruments and implantable devices.
- Cutting Tools
- Die Casting
- High Temp Applications
- Medical Components
- Wear Components

What’s the difference between TiAlN and AlTiN?
The difference in the description is due to the Al/Ti ratio in the film. TiAlN is typically 50/50 Al/Ti, while AlTiN has a higher concentration of aluminum, typically being 70/30 Al/Ti. (When tested head to head, AlTiN usually outperforms TiAlN.)
Since our coatings have a high percentage of Al in the film, our coating is more consistent with being an AlTiN coating than a TiAlN coating.
AlTiN is typically a black, or charcoal black in color, while TiAlN is often a dull brown in color.
