Cubic boron nitride(CBN) issecond only to diamond in hardness of superhard materials. It notonly has many good characteristics of diamond, and also has higherthermal stability and chemically inert for the iron group metalsand their alloys. As engineering materials, it has been widelyused  in processing industries in ferrous metal and alloymaterials. Because of the excellent performance in Thermal,electrical, optical and acoustic, it has been a functional materialwith prospects for development.

      Used in precision grinding,polishing and super-finishing, in order to achieve high-precisionmachined surface. Being suitable for resin, metal, ceramics bindersystem, it can be used for  production of sinteredpolycrystalline composite film, and also  be used as abrasivegain, grinding paste.
