BN Boron Nitride Nozzle

Boron nitride has excellent high-temperature resistance and corrosion resistance. High-purity boron nitride nozzles can withstand higher temperatures in a vacuum than low-purity BN nozzles. Due to the low wettability of boron nitride with metals, it is an ideal material for processing molten metals, especially for high-purity material metals in a vacuum.

In recent years, the additive manufacturing industry based on 3D printing technology has developed rapidly, and ceramics are increasingly used in special and complex parts. The basic raw material for metal 3D printing technology is a metal powder with high sphericity and narrow particle size distribution. The basic process for preparing and producing this powder is to melt the metal alloy and flow it through the nozzle. At the nozzle outlet, the molten metal is atomized by a high-pressure airflow and cooled into spherical particles at the same time. Therefore, the nozzle material needs to have high-temperature resistance, thermal shock resistance, fine processing ability, and resistance to liquid metal corrosion. We provide metal atomization powder and flow nozzles for 3D printing or powder metallurgy.
