CBN introduction

Cubic Boron Nitride CBN, abbreviated as: CBN or cBN. Currently, not found in nature, yet the presence of this substance is a hard synthetic material. Cubic boron nitride (CBN) is second only to cubic boron nitride in hardness of superhard materials. It not only has many excellent properties of diamond, but has a higher thermal stability and iron group metals and their alloys chemical inertness. It is used as engineering material, has been widely used in ferrous metal and alloy materials processing industries. polycrystalline diamond, it also its excellent thermal, electrical, optical and acoustic properties, has been applied in a series of high-tech fields, has become a promising functional materials.
