Cubic Boron Nitride Powder (cBN) Description:
Cubic Boron Nitride Powder is a finely ground form of cubic boron nitride, one of the hardest synthetic materials known, second only to diamond in hardness. This powder is composed of tiny, uniform cBN particles, which retain the extreme hardness, thermal stability, and chemical resistance characteristic of cubic boron nitride. Compared with traditional abrasives such as aluminum oxide and silicon carbide, CBN cubic boron nitride abrasive has high hardness, high wear resistance, and thermal conductivity. cBN powder is widely used in abrasive applications, coating technologies, and high-precision machining due to its excellent wear resistance and thermal stability.

Cubic Boron Nitride Powder (cBN) Applications
- Abrasive and Grinding Tools: Used in the production of grinding wheels, honing tools, and abrasive pastes for high-precision machining of hardened steels, superalloys, and other hard-to-machine materials.
- Polishing: Ideal for creating high-quality finishes on surfaces due to its uniform particle size and hardness, which can remove material evenly and produce smooth finishes.
- Wear-Resistant Coatings: Applied in thin coatings on cutting tools and other components to enhance wear resistance and extend their operational life.
- Thermal Management in Electronics: Due to its thermal conductivity, cBN powder is sometimes used as a filler in polymer composites or coatings for thermal management in electronics.
