99.95% Purity Niobium tube polished Niobium pipe
Niobium tube is a high-performance metal tube, mainly composed of niobium (Nb), a transition metal element with high melting point (2468 ° C) and boiling point (4742 ° C), and a density of 8.57g/cm ³. Niobium tubes typically have high purity, such as ≥ 99.95% or 99.99%, and comply with ASTM B394 standards. They can be provided in hard, semi hard, or soft states, with excellent corrosion resistance and high temperature resistance, and are widely used in the aerospace, electronics, and petrochemical industries.

1. Raw Material Selection
(The process begins with the selection of high purity niobium metal)
2. Melting and Casting
(The selected niobium metal is melted in a vacuum or inert gas environment)
3. Forming
(The niobium ingot is then processed through various forming techniques such as extrusion or rotational perforation to form a hollow tube shape)
4. Heat Treatment
5. Surface Treatment
(can be performed to remove any impurities or oxides on the surface of the tube)
6. Quality Control
7. Final Inspection and Testing
8. Packaging and Shipping
- Superconducting applications: Niobium is widely used in the production of superconducting materials, especially niobium-titanium (Nb-Ti) and niobium-tin (Nb3Sn) superconducting wires and cables. These materials are used in applications such as magnetic resonance imaging (MRI) machines, particle accelerators and magnetic levitation (maglev) trains.
- Aerospace: Niobium tubes are used in the aerospace industry for applications such as aircraft engines, gas turbine components, and rocket propulsion systems due to their high-temperature strength and corrosion resistance in harsh environments.
- Chemical processing: Niobium tubes are used in the chemical industry to produce corrosion-resistant equipment, such as heat exchangers, reaction vessels and piping systems that handle corrosive chemicals and high-temperature processes.
Niobium added to steel refines remarkably the cast structure and austenite structure of steel. An adequate and yet minimum quantity of niobium necessary for the refining control of austenite--grains in steel is 0.03 to 004%. 2. With an addition of niobium, the coarsening temperature of austenite-grains will rise.
Niobium is one of five refractory metals; this means it is highly resistant to extreme heat and wear. Its 4491°F (2477°C) melting point makes this metal and its alloys ideal for high pressure and high-temperature applications.
Niobium does not react with water under normal conditions. The surface of niobium metal is protected by a thin oxide layer.
