AlTiN/TiAlN COATING:
Aluminum Titanium Nitride (AlTiN) or Titanium Aluminum Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride. TiAlN offers higher temperature resistance than TiN, as well as slightly higher hardness and especially higher hot hardness (i.e. the hardness at high temperatures). It is primarily used in high temperature environments above the limits of TiN usage.

•         Hard (harder than TiN, harder than carbide, 3X hard chrome)
•         Enhanced temperature capability
•         Extremely high hot hardness
•         Strong adhesion—molecular bond to substrate metal.
•         Broad range of substrates
•         Uniform coating with no buildup on edges
•         Follows surface texture of the part.
•         Dark grayish metal appearance
•         Environmentally friendly process

Application:
The properties of the TiAlN coating make it suitable for high temperature cutting operations with minimum use of lubricant or dry machining. TiAlN is used successfully to machine titanium, aluminium and nickel alloys, stainless steels, alloy steels, Co-Cr-Mo and cast irons. TiAlN is also used to protect dies and moulds that are required to operate at high temperatures such as those in medium and hot forging and extrusion industries.
