Niobium is a grey, crystalline metallic element with high temperature resistance and other desirable properties for manufacturers. It is most commonly used in the creation of numerous metal alloys. Small amounts of niobium (as little as 0.1%) can significantly improve a metal’s performance characteristics. Advanced Refractory Metals offers pure, alloy and oxide niobium products in a variety of forms, including sheets, plates, rods, wires, tubes, strips, foils, and oxides.
1. Pure Niobium Sheet: High-purity niobium sheets with excellent corrosion resistance and ductility, used in aerospace, superconductors, and medical implants.
2. Tantalum Niobium Alloy Sheet: Sheets made from tantalum-niobium alloy, offering enhanced strength and heat resistance for high-temperature furnaces and aerospace components.
3. Tantalum Niobium Alloy Wire: Durable wires ideal for high-stress applications in electronics, superconductors, and heating elements.
4. Tantalum Niobium Alloy Rod/Bar: Solid rods or bars known for toughness, used in structural components, aerospace, and nuclear reactors.
5. Niobium Nickel Alloy Lumps: Lumps used in specialized industrial processes, such as superalloys and catalysts.
6. Molybdenum Niobium Alloy Ingots: Ingots combining high strength and heat resistance, ideal for high-temperature applications and aerospace.
7. Niobium Zirconium Alloy Ingots: Ingots known for superconductivity and durability, used in superconducting magnets and nuclear reactors.
8. Niobium Hafnium Alloy Foil: Thin foils with excellent thermal stability, used in aerospace, electronics, and high-temperature shielding.
Some of the most common uses of this element include:
* Steel Production
Niobium is commonly used in the microalloying of HSLA steels for the automotive and petrochemical industries. As little as 0.1% of this metal can considerably enhance the strength and stability of structural steel. Niobium-steel alloys are frequently used in automotive sheet steel and oil and gas pipelines.
* Superalloys
Superalloys are high-performance alloys that exhibit exceptional mechanical strength, thermal creep resistance, surface stability, and corrosion resistance. As much as 6.5% of niobium may be used in nickel, cobalt, and iron-based superalloys. These alloys are especially useful in the aerospace industry for the production of jet engine components, which can experience temperatures exceeding 1832°F (1000°C).
* Superconducting Magnets
When cooled to below niobium’s transition temperature, its resistance becomes negligible. Specific niobium alloys are used as type II superconductor wires for superconducting magnets. These magnets are critical components of magnetic resonance imaging equipment that is used in the medical industry.
