Application The atoms of c-BN are very light and very robust—mechanically and chemically, it is a very popular material. The most common use for c-BN is as an industrial abrasive. The similar properties it shares with diamond, and the fact that it is easier to find and produce, make this application logical. Since it will not dissolve or turn to liquid at high temperatures, it is also easy to use with iron, nickel, and similar metals.

Diamond, however, is soluble with these metals and would liquify at a lower temperature than c-BN—this leads to the breakdown of the grinding wheel, which is a necessary part of the process. If the grinding wheel is damaged, it can lead to burning and poor glazing or finish on the workpiece.

Specifically, the aviation industry and turbine manufacturers use electroplated precision grinding wheels to grind turbine blades and other engine components. They are best suited for close tolerance grinding that requires close stock removal of nickel alloys, cobalt alloys, and other hard materials. A wide variety of scratch-resistant surfaces, cutting tools, and drill bits have c-BN in their make up as well.
