AlTiN is a versatile coating that continues to find new uses. It is excellent for machining cast iron, high-nickel alloys, titanium alloys, hardened steels, stainless steels, and much more. AlTiN has also proven to be a good coating for metal-forming. AlTiN is good for higher temperature applications.
This is a good general purpose coating: the standard by which all other coatings are judged. TiN may be used in just about any application, such as cutting, forming, plastic injection molding components, fine blanking, etc. TiN is used quite frequently for medical and food processing applications.
TiCN offers improved hardness and wear resistance beyond TiN. This coating is recommended for tough machining applications such as high carbon steels, high silicon aluminums, and tool steels. TiCN is also good for stamping and forming tools.
Many applications for TiAlN coating are similar to AlTiN coating. However, TiAlN is slightly less brittle and more ductile than AlTiN: this makes it better for roughing and interrupted cut applications. TiAlN is a better choice when coating lower grade or questionable substrates, as it can be more forgiving.
This is another good general purpose coating. Many of its properties are similar to TiN. ZrN is good for machining titanium, cast iron, and non-ferrous materials such as aluminum, copper, and brass. ZrN is also used in decorative applications.
In comparison with TiAlN, the CrAl*N coatings showed a higher abrasion resistance, particularly for coatings with a hardness higher than 30GPa. The present study clearly demonstrates the advantages of CrAl*N over other existing similar coatings for high-speed machining.. An evident improvement in the performance of the CrAl*N-coated end-mills was observed compared to the TiAlN-coated ones for cutting a hardened tool steel under high speed dry machining conditions.

When tools are heavily stressed when machining, with high mechanical and thermal strains. Nonetheless, productivity has to be increased. The top level all-rounder for cutting, punching and die casting. With this coating we were able to significantly excel the performance curve of the already coating. This results in an extremely wear resistant coating with excellent hot hardness and thermal shock stability.
