Hexagonal Boron Nitride has a microstructure similar to graphite. This structure of multiple layers of tiny flakes provides excellent machinability and low friction properties. That is why Hexagonal Boron Nitride (HBN) is also known as white graphite. Edgetech can provide Boron Nitride Tubes in a variety of custom specifications:
Outside Diameter: >3mm
Inside Diameter: >2.5 mm
Wall Thickness: >0.5 mm
Length: <480 mm
Our Boron Nitride Tubes have the following notable properties:
High temperature resistance, good thermal shock resistance
High thermal conductivity
Low thermal expansion
High electrical resistance
Low dielectric constant and loss tangent
Microwave transparency
Non-toxic
Easy to process – non-abrasive and lubricious
Chemically inert
Non-wetting by most molten metals
