In the TIG welding of steel tubes in heat exchanger cores, Syalon 101 nozzles have outlasted alumina nozzles by a factor of 10 to 1. In a plasma welding operation, Syalon 101 nozzles were found to be ...

These can allow precise welding of captive nuts to sheet metal, and are therefore widely used in the metal forming industry. Sialons are silicon nitride-based advanced ceramics that have excellent ...
