Our ceramic nozzle are made of silicon nitride ceramic material.The welding nozzle has specifications of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, etc. The mouth slope standard is 5mm, and nozzles with different inclinations can be customized.
Silicon nitride ceramic materials have excellent thermal stability, strong oxidation resistance and high dimensional accuracy. They do not bond with precious metals such as gold and silver when the jewelry is melted, and do not react. It is the best welding nozzle. material. The company’s silicon nitride burner material is one of the hardest substances in the world. It is extremely resistant to high temperatures, its strength can be maintained to a high temperature of 1300 ° C without falling, it will not melt after heating, will not decompose until 1900 ° C, and has amazing chemical resistance, can withstand almost all inorganic acids and 30% Hydrofluoric acid.
