What is AlTiN?
AlTiN is an acronym for Aluminum Titanium Nitride. AlTiN is a dark colored vapor deposition coating that is applied in a vacuum. AlTiN is so tough and hard it is used to coat machine tools, drill bits and other wear surfaces to make them last longer. In addition to wearing better than hardened steel, AlTiN imparts a beautiful purple-black color to the surface it is applied to. We use AlTiN to provide a dark non-glossy coating to our stainless steel bezels. We have found that this coating will out wear even a military Type 3 hard anodize.
