Product Description

Features & Benefits

  • High hardness: Boron carbide is one of the hardest materials known, with a Mohs hardness of 9.3.
  • Wear resistance: Boron carbide is also highly resistant to wear, making it ideal for cutting tools that need to maintain their sharpness over time.
  • Chemical resistance: Boron carbide is resistant to most acids and alkalis.
  • Low density: Boron carbide is lightweight compared to other ceramics, which can help reduce the weight of cutting tools.
  • High melting point: Boron carbide has a high melting point of over 2,700°C, making it suitable for high-temperature applications.

Markets & Applications

  • Cutting tools: Boron carbide inserts are commonly used in metalworking applications to machine hard materials such as cast iron, hardened steel, and superalloys.
  • Armor: Boron carbide is also used in armor applications, such as body armor and vehicle armor, due to its high hardness and ability to withstand high-velocity impacts.
  • Nuclear industry: Boron carbide is used in the nuclear industry as a neutron absorber and control rod material.
  • Semiconductor industry: Boron carbide is used in the semiconductor industry as a polishing and lapping material for silicon wafers.
