Niobium Wire Production Process
- Matières premières: Sélectionnez des produits de haute pureté niobium powder.
- Métallurgie des poudres: Mix with binder and compact into a green billet.
- Frittage: High-temperature sintering to remove the binder and increase density.
- Drawing: Draw the rod to achieve the desired size and finish.
- Traitement thermique: Anneal to relieve stress and enhance properties.
- Traitement de surface: Clean and polish the surface.
- Cutting & Customization: Cut or customize according to requirements.
Niobium Wire Processing Method
- Frittage
- Forgeage
- Rotary Forging
- Roulant
- Polishing
Niobium Wire Surface Finish
Depending on the intended applications, niobium tubes and pipes have three main surface finishes as follows:
- Black: The surface is “as swaged” or “as drawn”, retaining a coating of processing lubricants and oxides.
- Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
Niobium Wire Applications
- Matériaux supraconducteurs: Niobium wires are widely used in the field of superconductivity and are commonly used to produce superconducting cables, superconducting magnets, and other devices, especially in particle gas pedals and nuclear magnetic resonance (NMR) instruments.
- Nuclear Industry: Niobium wires are commonly used as structural materials in nuclear reactors and nuclear fuel jacket materials due to their low neutron capture cross section and high corrosion resistance.
- Aérospatiale: Due to its excellent high-temperature strength and heat resistance, niobium wire is often used to manufacture high-temperature components, such as engine components for rockets and airplanes.
- Electronic Components: Niobium wires are used as acid and liquid metal corrosion-resistant materials in manufacturing boilers, heaters, and other equipment.
- Industrie chimique: Niobium wires are used as acid and liquid metal corrosion-resistant materials for boilers, heaters, and other equipment.
Niobium Wire Packaging
The Niobium Wire is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
