Product Introduction

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