Dual structure solution

Cross section BALINIT® ALDURA

Its novel dual coating structure unites and enhances the strengths of proven systems:

Support layer
A perfectly adapted TiAlN base coating ensures excellent adhesion and affords great mechanical strength.

Functional layer
The nanocrystalline AlCrN-based coating features excellent hot hardness, resistance to oxidation and thermal insulating properties.

This combination opens the door to a new realm of performance in hard machining and in processes with difficult-to-machine materials.

Recommended applications
  • On solid carbide end mills for roughing and finishing
  • Machining of hardened steels (>60 HRC)
  • High speed cutting (HSC)
  • Cutting of difficult-to-machine materials
