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.
