Applications
Niobium and niobium alloyed bars, rods and wires own a high melting point, corrosion resistance, good cold processing properties and other superb features. Now it they are more and more widely used in chemical, electronic, lighting source, aerospace and other areas. Like tantalum, niobium can be also used in making vaccum furnaces' attachments and supports of high temperature in technical ways. Niobium of high purity, NbTi, Nb3Sn and alloyed niobium are also a good superconductor. The surface of metals will show different colors due to different amount of oxygen. So, niobium is also applied to jewelry manufacture industry.
