VARIANTIC - The layer with high oxidation resistance

The old-pink colored VARIANTIC layer, abbrev. TiAlCN, represents a worthwhile alternative to the TiCN pure coating.

It indicates the following properties:

  • Low friction
  • High oxidation resistance

Applications:

  • Cutting:
    Milling, turning, drilling and cutting for the processing of high-alloy and low-alloy steels with high feeds and cutting speeds; very well suited for HSS endmills in the area of steel machining.
  • Forming:
    Drawing, stamping, pressing and forming tools for the machining of high-alloy and low-alloy steels and e.g. stainless steel sheets.

Deposition technology:

The deposition of the VARIANTIC layers is performed by means of PVD technology. This allows the deposition of the coatings on tool steels, HSS, cemented carbides or many other materials with temperatures less than 450° C.

In numbers:

Material: Titanium-aluminum carbon nitride, TiAlCN (multi-layers)
Microhardness HV 0.05: 3500 ± 500
Coefficient of friction against steel 100Cr6: 0.2
Layer thickness [µm]: 2 – 4 [1]
Maximum application temperature: 800° C / 1470° F
Color: altrosa
General characteristic: Low friction, high oxidation resistance
Preferred applications: For a large range of cemented carbides, Cermet and HSS tools; All steel grades in case of dry, semi-dry (MMS) as well as wet machining conditions; Excellent for the drilling of steel; drawing, stamping, pressing and forming tools for the machining of high-alloy and low-alloy steels

[1] Dependent on tool size, for micro-tool also of less than 2 µm.
