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.
