Application：
niobium and niobium alloy tube with high melting point,good corrosion resistance,cold working performance characteristics.Wildly used in chemical industry,electronic,aviation and aerospace industry.Is mainly used in the production of high pressure sodium lamp, aviation and aerospace engine structure material, chemistry reaction vessel, heat exchanger tube, reactor internal components and coating materials.Add zirconium in niobium can obviously improve the oxidation resistance and strength, the niobium zirconium alloy is manufactured into capillary supply sodium lamp manufacturing.
