A new development in high-performance materials is gaining attention in the metal powder production industry. Boron nitride ceramic rings are now being used as nozzle inserts for centrifugal atomization of cobalt chrome alloys. These rings offer strong performance under extreme heat and mechanical stress.

Centrifugal atomization requires parts that can handle very high temperatures without degrading. Traditional metal nozzles often wear out quickly or react with molten cobalt chrome. Boron nitride solves this problem. It stays stable at high temperatures and does not stick to molten metal. This helps produce cleaner, more consistent metal powders.
Manufacturers report longer service life and less downtime when using boron nitride inserts. The material’s low thermal expansion also means it keeps its shape during repeated heating and cooling cycles. This stability leads to better control over the atomization process. Powder quality improves as a result.
The use of boron nitride also cuts maintenance costs. Operators replace parts less often. There is less risk of contamination in the final powder product. This matters for industries like aerospace and medical devices where purity is critical.
Suppliers are ramping up production of these ceramic rings to meet growing demand. They are working closely with powder producers to fine-tune dimensions and tolerances. Early adopters say the switch has made their operations smoother and more efficient.

Boron nitride’s unique mix of thermal resistance, non-wetting behavior, and mechanical strength makes it ideal for this demanding application. As additive manufacturing grows, so does the need for reliable, high-quality metal powders. Boron nitride ceramic rings help meet that need.
