Description

INNOVACERA® Hot Press Boron Nitride Rod Diameter 12.7 mm, two length in stock (25 mm, 200 mm), custom length is available. White in color.

Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials this structure, made up of layers of tiny platelets, is responsible for excellent machinability and low-friction properties. we called hexagonal boron nitride (HBN) or white graphite.

Features of Boron Nitride

  • High thermal conductivity
  • Low thermal expansion
  • Good thermal shock resistance
  • High electrical resistance
  • Low dielectric constant and loss tangent
  • Microwave transparency
  • Non toxic
  • Easily machined — non abrasive and lubricious
  • Chemically inert
  • Not wet by most molten metals
