Nozzles

Boron nitride nozzles are commonly used in high-temperature and high-pressure industrial applications such as:
Metalworking
Chemical processing
Aerospace
Semiconductor manufacturing
Glass manufacturing
boron nitride nozzles are valued for their high temperature and chemical resistance, which make them ideal for use in harsh industrial environments.

PRODUCT DESCRIPTION
