Leidenschaft für Diamant / Passion for Diamond


Boron nitride powder is the source material for the manufacture of cubic boron nitride, which has been available since the late 60s. It is manufactured under high pressure and at temperatures of over 1500º C. Cubic boron nitride is now regarded as the second hardest substance after diamond.

Cubic boron nitride is preferred over diamond in many applications, since it is stable at temperatures up to 1400º degrees in air. Diamond starts to decompose from 800º C. A further characteristic as compared to PCD is the chemical resistance to ferrous materials.

Areas of application:
Hard machining, GG, GGG, sintered metal, super alloys.
