Monocrystalline Cubic Boron Nitride (CBN) Superabrasive Powder
Cubic Boron Nitride (CBN) is second only to diamond in hardness but it has two times the thermal stability of diamond. CBN has four times the wear resistance than that of traditional abrasives and its has extraordinary thermal conductivity. It is designed for fine grinding and polishing in a variety of demanding surface finishing applications, such as metal bond grinding wheels, resin bond grinding wheels, vitrified bond wheels and electroplated products.
| Material | Cubic Boron Nitride (CBN) |

| Bulk modulus (GPa) | 367 |
| Microhardness (GPa) | 75-90 |
| Melting point (K) | 3500 |
| Expansion coefficient (10−6/K) | 4.7 |
| Thermal conductivity (kW/m·K) | 1.3 |
| Thermal stability (K) | 1573~1673 |
In order to choose the optimum monocrystalline CBN super-abrasive powder for your application, please consider the following the following properties:
- Power Color
- Particle size and particle size distribution (PSD)
- Particle shape / morphology / aspect ratio / ellipticity
- Toughness and thermal toughness index
