Application:


Niobium and niobium alloy tubes have the characteristics of high melting point, corrosion resistance, and good cold working performance. They are widely used in the chemical industry, electronics industry, aviation and aerospace industry, and are mainly used to make high-pressure sodium lamps, structural materials of aviation and aerospace engines, Reaction vessels, heat exchanger tubes, reactor internal components and cladding materials for chemical processes, etc. Adding zirconium to niobium can significantly improve the oxidation resistance and strength of the material. Currently, niobium-zirconium alloy is manufactured into capillary tubes and supplied to the sodium lamp manufacturing industry.
