    Niobium metal plates, sheets, wire, rod, tubing

    - Sputtering targets.
    - Cathode protection systems for large steel structures.
    - Chemical processing equipment.

    Corrosion resistance, formation of oxide and nitride films. Increase in high temperature resistance and corrosion resistance, oxidation resistance, improved creep resistance, reduced erosion at high temperatures.

    Niobium-titanium alloy
    Niobium-tin alloy

    Superconducting magnetic coils in magnetic resonance imagery (MRI), magnetoencephalography, magnetic levitation transport systems, particle physics experiments.

    Electrical resistance of alloy wire drops to virtually zero at or below temperature of liquid helium (-268.8°C).

    Niobium-1%zirconium alloy

    - Sodium vapor lamps
    - Chemical processing equipment

    Corrosion resistance, fixation of oxygen, resistance to embrittlement.

    Vacuum-grade ferro-niobium and nickel-niobium

    Superalloy additions for turbine blade applications in jet engines and land-based turbines. Inconel family of alloys, superalloys.

    Increase in high temperature resistance and corrosion resistance, oxidation resistance, improved creep resistance, reduced erosion at high temperatures.
