cBN-BMA. Medium Friability. Angular Shape. Density 3.48 g/cm3. Black, medium strength, with an angular morphology and high thermal stability. The BMA's angular morphology produces a free cutting action that reduces heat generation and power consumption while increasing grinding efficiency. Resin Bond. Vitrified Bond.

Cubic boron nitride is a synthetic crystalline material second only to diamond in Knoop hardness. Although softer than diamond, CBN is superior in terms of abrasion resistance and oxidation resistance with steel alloys. Its relative crystalline inertness makes CBN the abrasive of choice for grinding steels, cast iron and nickel-based alloys.

Cubic boron nitride (CBN) is an allotropic crystalline form of boron nitride almost matching the hardness of diamond. Cubic boron nitride was first synthesized in 1957. The hexagonal crystals are obtained at 2,800°F− 3,700°F and pressures of 3.45 to 6.2 MPa (0.5 to 0.9 × 106 psi), in the presence of catalyzers such as alkali metals ...

Cubic boron nitride is commonly known as BorazonTM CBN, and is a man-made synthetic abrasive. CBN is made from cubic boron nitride grains bonded by ceramic material. It is as hard as diamond on the Mohs scale, making it well suited for ferrous materials in lapping operations, as it will not carbonize when interacting with iron (Fe), as diamond ...

Vitrified Bond. cBN-X45. Medium Friability. Angular Shape. Density 3.48 g/cm3. Dark to light brown in color in equal ratio, angular with some irregular particles in shape. The CBN-X45 tends to macrofracture under impact loading, along with its high thermal stability and free …

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.
