Niobium

Niobium is relatively lightweight and can maintain its strength at elevated temperatures and is used extensively in aerospace equipment and missiles. It is often used as an alloying agent to improve the strength of specialty steels and other metals.

Niobium is a ductile metal that exhibits excellent corrosion resistance to liquid metal. Niobium superconducts at low temperatures and has the melting point of 2477° C (4491° F).

ATI produces Niobium alloys in the following forms:

  • Bar
  • Rod
  • Billet
  • Tube
  • Chips
  • Sheet
  • Foil
  • Strip
  • Powder
  • Wire
  • Precision Machined Components
