Russian company begins production of cubic boron nitride superhard cutting tools

A Russian company began producing superhard cutting tools made of nano-cubic boron nitride powder. Cubic boron nitride is one of the superhard materials, and its hardness is only 20-40% lower than that of the hardest diamond. It has good microhardness, ductility and thermal resistance. This composite does not react with carbon, so it can process steel materials, cobalt and hard alloys. The company's products will be sold to the CIS countries, Europe, China and the United States. The Russian cubic boron nitride tool market, which is expected to account for 30%, will export $3 million in 2011. After the company's second production line is completed, its production capacity can be expanded by 10 times.
