Titanium Aluminum Nitride (TiAlN or AlTiN)


Titanium Aluminum Nitride (TiAlN) coating is recommended for applications where heat resistance and extra hardness is required for abrasive materials. A formed layer of aluminum oxide gives this tool better life in high heat applications. This coating is primarily selected for carbide tooling where little to no coolant is being used. TiAlN has a surface hardness in the upper 80 Rc range with a coefficient of friction less than Titanium Nitride (TiN). TiAlN is a high-performance coating which excels in abrasive and difficult-to-machine materials such as cast iron, aluminum alloys, tool steels, and nickel alloys.
