With high melting point, excellent anti-corrosion property and workability in cold environment, Nb and Nb alloy tubes are widely used in chemistry, electronics, aviation and aerospace industry. They can be used as material for high pressure sodium lamp, nozzles and structural parts for airplane engines, anti-corrosion parts under strong acid environment in chemical processing industry.
By adding zirconium in niobium, the hardness and antioxidant properties can be greatly improved. In nowadays, a large quantity of tiny tubes is be used as anode leads for capacitors.
