Overview of PCBN CBN Insert CNGA type polycrystalline cubic boron nitride for Machining powder metal hardened steel gray iron
Boron Carbide (B4C) is a ceramic compound renowned for its exceptional hardness and wear resistance, ranking just below diamond and cubic boron nitride in terms of hardness. Composed of boron and carbon atoms arranged in a covalently bonded crystal structure, it exhibits unique physical and chemical properties that make it highly valuable in various industrial and military applications. Boron carbide’s high melting point, low density, neutron-absorbing capability, and extreme toughness further distinguish it among advanced materials.
Features of PCBN CBN Insert CNGA type polycrystalline cubic boron nitride for Machining powder metal hardened steel gray iron
-
Extreme Hardness: With a Mohs hardness of around 9.3 to 9.5, boron carbide is one of the hardest materials known, surpassed only by diamond and cubic boron nitride.
-
Lightweight: Despite its hardness, boron carbide has a relatively low density of about 2.52 g/cm³, which makes it an attractive material for lightweight armor systems.
-
Thermal Stability: It possesses excellent thermal stability, maintaining its properties up to temperatures around 2,000°C, making it suitable for high-temperature applications.
-
Neutron Absorption: Boron carbide is a potent neutron absorber due to its boron content, making it ideal for nuclear shielding and control rods.
-
Chemical Resistance: Resistant to most acids and alkalis, except for hydrofluoric acid and hot concentrated alkaline solutions, ensuring durability in corrosive environments.
-
Abrasion Resistance: Its exceptional wear resistance makes it suitable for applications where friction and abrasion are prevalent, such as sandblasting nozzles.

Parameters of PCBN CBN Insert CNGA type polycrystalline cubic boron nitride for Machining powder metal hardened steel gray iron
PCBN (Poly carbide Nitride) is a hard, wear-resistant material that can be used as a substitute for steel or aluminum in certain types of manufacturing processes. CBN insert tools are used to create additional features on the surface of metal parts, such as holes and graduating edges.
CNGA stands for Carbon Nanotubes in Agarite matrix, which refers to the combination of carbon nanotubes with agarite matrix. The use of this material provides several advantages over traditional materials:
1. Improved machinability: CBN has a high hardness and wear resistance, making it well-suited for machining applications.
2. Enhanced surface finish: CBN inserts can produce sharp, precise edges and holes, resulting in improved surface finish.
3. Reduced weight: Since CBN is made from carbon, it has a lower density than conventional materials, which results in a lighter weight.
The parameters you mentioned are likely specific to the tooling process you are referring to. Without more information about the specific application, it is difficult to provide accurate recommendations. However, generally speaking, the choice of material will depend on factors such as the desired properties of the final product, the desired tool life, and the cost considerations.
