Uses: Niobium and niobium alloy tubes have high melting point, corrosion resistance, good cold working properties, etc. They are widely used in the chemical industry, electronics industry, aviation

In the aerospace industry, it is mainly used to make high-pressure sodium lamps, structural materials for aviation and aerospace engines, reaction vessels for chemical processes, heat exchanger tubes, internal elements of reactors

The material is used in the production of the niobium and zirconium alloys. The addition of zirconium to niobium can significantly improve the oxidation resistance and strength of the material, and currently niobium-zirconium alloys are

Manufactured into capillary tubes to supply the sodium lamp manufacturing industry.
