With high melting point, excellent anti-corrosion property and workability in cold environment, Nb and Nb alloy tube, rod and wire are widely used in chemistry, electronics, aviation and aerospace industry. They can be applied as nozzles and structural parts for airplane engines, inside elements and protection material for nuclear reactor, anti-corrosion parts under strong acid or environment.
By adding zirconium in niobium, the hardness and antioxidant properties can be greatly improved. A large quantity is be used in high pressure sodium lamp and anode leads for capacitors.
