The Multi-Functional Multi-Layer Coating

Tough, hard and resistant to temperatures of up to 800° C – surface treatment using VARIANTIC titanium aluminium carbon nitride coating always delivers excellent results: in machining, metal forming, punching and fine-edge blanking applications alike. The temperature-resistant TiAlN substructure, together with a TiCN top coat that is both hard and has good sliding properties, results in a perfect combination yielding significant advantages in many areas of application.

Perfect for Many Applications

Thanks to its multi-layer structure, the multi-functional VARIANTIC coatings are the perfect choice for many areas of application. Surface treatment using Variantic yields significantly improved wear resistance and high oxidation resistance. This makes VARIANTIC a popular choice in the drilling of steel.
Besides carbide metal and HSS tools, Cermet tools and all types of steel machining (lubricated, MMS or dry) belong to the preferred fields of application.

An Option for the Field of Metal Forming

In the field of metal forming, the VARIANTIC coating system is especially well suited for the machining of high-tensile steels. Thanks to surface treatment using VARIANTIC by means of the DUPLEX method, one can achieve further optimisation of the results.
