      Cubic Boron Nitride(CBN) or Diamond?

      CBN has the zinc-blende crystal structure equivalent to diamond, the hardness is a little below diamond.CBN has technological and economic advantages compare to diamond. The hardness of CBN work pieces is as low as 50 HRC but not brittle.

      Diamond is the hardest material know now, with a Moh's harness of 10.Compare with CBN,diamond is used for grinding hard but brittle and short-chipping materials, such as tungsten carbide,glass,ceramics,quarz,graphite and so on.
