Bernex™ 29 HSA Al2O3
Bernex™ 29 HSA
Bernex™ 29 HSA is exceptionally well-suited for high-volume machining of cast iron and cast steel at medium to high cutting speeds and high temperatures due to the thermo-dynamically stable structure of its ceramic content.
The αAl2O3 layer, as a functional layer, not only exhibits an exceptional hot-hardness, it also features a very low thermal conductivity, which significantly increases tool lifetime. TiN, as a surface layer, protects the hard ceramic αAl2O3 layer from wear damage during the cutting start-up phase.
Bernex™ 29 HSA is applied at ca. 1000 °C by means of CVD and is suited for cemented carbide cutting inserts.
