Boron nitride blanks are often the raw material for other machined parts. BN blanks are made from 99% pure composite BN material formed at high temperature (1900C). It could also be applied directly as insulators in some electronic or vacuum equipment with simple machining. We offer high-quality BN Blanks to our customers at competitive prices.

Boron Nitride Blank Advantages:

-Low wettability to molten metal

-Relatively high thermal conductivity with low thermal expansion

-Relatively high thermal shock resistance

-Extremely high working temperature with proper inert gas protection

Packing

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Blank is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
