Cubic boron nitride is an ultra-hard material with hardness second only to diamond. It not only possesses many excellent characteristics of diamond but also has higher thermal stability and chemical inertness to ferrous metals and their alloys, making it widely used in many fields.
Cubic boron nitride has extremely high hardness and wear resistance, making it the ideal material for manufacturing high-speed cutting tools and grinding wheels. It is especially suitable for cutting difficult-to-machine materials such as titanium alloys, high-temperature alloys, ceramics, and glass. Compared to other materials, cubic boron nitride tools have a longer lifespan and higher processing efficiency, greatly improving production efficiency and reducing production costs, such as in high-speed cutting tools, bearings, bushings, etc. Additionally, coatings of cubic boron nitride can also enhance the wear resistance and corrosion resistance of mechanical components.
Cubic boron nitride has excellent high-temperature stability and can maintain its hardness and mechanical properties at high temperatures, making it widely used in the manufacture of high-temperature components. For example, it can be used to manufacture high-temperature bearings, jet engine turbine blades, high-temperature furnace linings, etc. The service life and reliability of these components have been significantly improved.
Cubic boron nitride has good electrical insulation and thermal conductivity, making it widely used in high-frequency electronic components, semiconductor devices, and other fields. For example, it can be used as substrates for high-frequency current amplifiers, power transistors, LED packaging, optical communication devices, etc., effectively improving the efficiency and performance of the equipment.
Cubic boron nitride still maintains stable physical properties in extreme environments such as high temperature, high pressure, strong corrosion, and high speed, and is therefore widely used in the aerospace field. For example, it can be used as rocket nozzles, thermal insulation materials, thermal conductive components, etc.
Cubic boron nitride has strong corrosion resistance and can be used in harsh chemical environments such as strong acids, strong alkalis, high temperatures, and high pressure. Therefore, it also has a wide range of applications in the chemical industry, such as catalysts, corrosion-resistant transportation pipelines, and furnaces.
Cubic boron nitride has biological inertia and is less likely to cause tissue rejection reactions, making it widely used in the medical device field. For example, it is used in coatings for biomedical materials and artificial bones.
In summary, the application range of cubic boron nitride is very extensive, not only used in traditional industries such as cutting tools, high-temperature components, and electronic components but also has broad application prospects in emerging fields such as medicine and biomedicine. In addition, cubic boron nitride is also widely used in the fields of abrasives, bulletproof materials, and biochemical sensors. As a new material, cubic boron nitride has a very broad application prospect and can promote the continuous development of modern industrial technology.
