Niobium rod and niobium bar are forged from metal niobium, and high-purity niobium metal has high ductility.

Adding zirconium to niobium can obviously improve the oxidation resistance and strength of the material. Niobium and niobium zirconium alloy wires are widely used in the manufacture of high pressure sodium lamp and anode leads of electrolytic capacitors.
