Cubic Boron Nitride (CBN) is a super-hard material second only to diamond in hardness. It not only has many excellent properties of diamond, but also has higher thermal stability and chemical inertness to iron-group metals and their alloys. Its hardness and chemical properties make CBN particularly suitable for grinding ferroalloys and other aerospace materials. The use of cubic boron nitride is a great contribution to metal processing, leading to revolutionary changes in grinding and the second leap in grinding technology. The series of CBN has been widely used in high-tech fields such as aerospace, automobile military industry, wind power, metallurgy and electrical appliances.
