Cubic Boron Nitride (CBN) monocrystalline has the most thermal stability, its hardness is just second to diamond. The synthetic CBN crystal is converted from hBN under extremely high pressure (6 G Pa -7 G Pa) and temperature (1400 ℃ ~1500℃). CBN will not react with iron and nickel (steel and super alloy).

Application
The combination of thermal and chemical stability and hardness make CBN to be widely applied in automotive and aerospace industries, tool and cutter grinding, gear and bearings machining etc

Products Available
