Uses
Niobium and niobium alloy pipes have the characteristics of high melting point, corrosion resistance and good cold workability. They are widely used in the chemical industry, electronics industry, aerospace and aerospace industries. They are mainly used to make high-pressure sodium lamps, structural materials for aviation and aerospace engines, Chemical process reactors, heat exchanger tubes, reactor internal components, and jacket materials. Adding zirconium to niobium can significantly improve the oxidation resistance and strength of the material. At present, niobium-zirconium alloys are manufactured into capillaries for the supply of sodium lamps.
