WebThe coating offers high surface lubricity, reduces friction, and increases chip flow. The resistance in heat and hardness allows the tool to run about 20-30% higher machining speeds than uncoated end mills. Titanium Carbonitride (TiCN) is harder than Titanium Nitride (TiN) at low cutting temperatures. WebAlTiN Coatings General Information Can withstand elevated temperatures up to 800°C (1450°F) in air. Forms a thin surface layer of Al2O3 that is hard, low in friction and oxidation resistant. As this layer wears, it is constantly rebuilt from the Al in the coating. Performs best in high temperature applications.
