Niobium Applications
Applications areas ofNiobiumexpand. The metal is an alloying element to fortify high strength; it has a low capture cross-section for thermal neutrons,niobium alloystemperature- and corrosion resistant, gettering and superconducting properties as well as electron work function, good cold pressure shaping and weldability determined its applications in rocket, missile, aviation and space-system engineering, (radio)electronics, chemical instrumentation technology, and nuclear power supply.Pure niobiumand its alloys are used in aviation manufacture, production of nuclear reactor fuel elements, pipline and capacities construction for liquid metals, electrical capacitors parts, anodes, cathodes and other equipment for radars, powerful electronics, and corrosion-resistant chemical apparatus.Niobiumis used for uranium doping, cryotron manufacturing.Nb3Sn stannide and Ti/Zr alloys are used in superconductive solenoids materials.Niobiumis a good Tantalum substitute since it is cheaper and lighter.Niobiumhas a number of uses: it is a component of some stainless steels and an alloy of other nonferrous metals. It is also a very important alloy addition in HSLA steels, which are widely used as structural components in modern automobiles.
