Niobium and niobium alloy tubes with a high melting point, high corrosion resistance, and good cold performance, characteristics, is widely used in chemical industry, electronics industry, aviation and aerospace industry, mainly for the production of high-pressure sodium lamp, aviation and aerospace engine structural materials, chemical process the reaction vessel and heat exchanger tube, the reactor internal components and sheath materials. Adding zirconium in Niobium can significantly improve the oxidation resistance of the material and strength.
