Hard Coating Series
AlTiN coatings offer high hardness and a good stability at high temperatures. They are applied on thermally stressed tools at medium and high cutting speeds.
In combination with a low affinity with friction welding, AlTiN is excellent for machining of hard steels or Titanium alloys.
As a further development of AlTiN-coatings AlTiN+ has higher hardness. At the same time the multilayer structure of the coating minimizes possible crack formations. In total the lifetime of AlTiN+ coated tools is increased when machining hard materials.
AlTiN-coatings are available in different compositions, i.e. the amount of Aluminum and the corresponding Ti-proportion can be widely varied in quantity. Ultimately the composition of the coating is determined by the application requirements.
We offer the following AlTi-based Coatings designed for your applications:
(*) Nanohardness, deviations +/- 3 GPa
