Cubic Boron Nitride

As the second hardest abrasive we knew, Cubic Boron Nitride (CBN) is synthesized from similar process to that for synthetic diamond.

CBN is of good thermal stability. Even at higher temperature, CBN could still remain its hardness. The abrasive is widely used for grinding ferrous materials for which diamond is not suitable due to its reaction to iron at higher temperature.

CBN product line of Cutall Superabrasives includes grits and micron powders.
