AlTiN Coated Tungsten Carbide Milling Tools’ Features

It is known that the AlTiN is a thin film coating that was developed from Titanium Nitride with more aluminum content, which enables AlTiN coated tungsten carbide milling tools offer higher temperature resistance than the ones with TiN, as well as slightly higher hardness and especially higher hot hardness. In general, the advantages of AlTiN coated tungsten carbide milling tools comprise as follow.



It proves that AlTiN coated tungsten carbide milling tools could withstand elevated temperatures up to 800°C in air. It operates well in high temperature applications, as it could offer an outstanding bound-a low in friction and oxidation resistant thin Al2O3 surface layer, which could constantly rebuilt and require high temperatures to form. AlTiN coated tungsten carbide milling tools typically last 3 to 10 times longer than uncoated tools.
