Superhard Abrasive Cubic Boron Nitride Powder

• 

Cubic Boron Nitride, that is CBN, is kind of synthetic super hard material. With a high hardness ofhv7200-9800mpa, its hardness is justlower than that of diamond. Like diamonds, CBN is an insulator but an excellent heat conductor. The structureof the boron nitride formis similar toitof diamond, also known as cube boron nitride, c-BN, β-BN, or z-bn. It is widely used as an industrial drilling and grinding tool.

Various black, amber and brown CBN in different sizescan be supplied as following:

CBN grit: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400 mesh

CBN micron powder: 1-3, 2-3, 2-4, 3-6, 4-8, 5-10, 6-12, 7-14, 8-16, 10-20, 12-22, 15-25, 20-30, 22-36, 30-40, 35-45, 40-60 micron

Characteristics of CBN Powder

Cubic boron nitride (CBN) is a superhard material, whichhardness is next to that of diamond. It not only has many excellent propertiesasdiamond, but also has higher thermal stability and chemical inertness to ferrous metals and alloys. As an engineering material, it has been widely used in ferrous metal and its alloy material processing industry.Meanwhile,the CBNhas been applied in a series of high-tech fields with its excellent thermal, electrical, optical and acoustic properties, and has become a functional material with development prospects.

Application ofCBN Powder

Cubic boron nitride powder is used in precision grinding, polishing and ultra precision machining to achieve high precision machining surface. It is suitable for resin, metal, ceramic and other binder systems, as well as for the production of polycrystalline composite sinter, loose abrasive and grinding paste.

Withexcellent chemical and physical properties, such as high hardness, high thermal stability and chemical inertness,theblack CBN has been widely used as superhard abrasives in different industries, and now it has become an indispensable important material in automobile, aerospace, mechanical electronics, microelectronics and other industries, so it has also been developed in various industries The state attaches great importance to it.
