What Is Cubic Boron Nitride
Jul 30, 2024
Cubic boron nitride (CBN) is a superhard material that is mainly used for cutting and grinding applications. It is made by synthesizing boron nitride crystals and compressing them at high pressure and temperature.
CBN is the second hardest material known to man after diamond, making it an excellent choice for cutting and grinding tough materials like hardened steel, nickel-based alloys, and cast iron. Its hardness and abrasion resistance make it more effective than other materials for material removal, resulting in a higher rate of production and reduced downtime.
Apart from its excellent mechanical properties, CBN is also chemically inert, which means it is resistant to most chemicals and acids. It also has a low coefficient of thermal expansion, which means it remains stable at high temperatures, making it useful for high-temperature applications.
CBN also has the ability to conduct heat and electricity, making it suitable for use in electronic applications and heat sinks. It has been used in the production of electronic components and semiconductors due to its excellent thermal conductivity.
