Description
Niobium is a soft and ductile metal, which makes it a good material for tubes, pipes, and even capillary tubes. The purity of the niobium can be up to 99.95%.The niobium tube is made by extrusion, tube reduction, or deep drawing with the plate.Niobium and niobium alloy tubes, rods and wires are widely used in the fields of chemistry, electronics, aviation and aerospace because of their high melting point, corrosion resistance and good cold working performance. Niobium and niobium alloy bars are used as structural materials for aircraft engines and rocket nozzles, reactor internal components and cladding materials, and to make corrosion-resistant parts under conditions of nitric, hydrochloric, or sulfuric acid corrosion. Adding zirconium to niobium can obviously improve the oxidation resistance and strength of the material. Niobium and niobium zirconium alloy wires are widely used in the manufacture of high pressure sodium lamp and anode leads of electrolytic capacitors. Niobium Tube and Niobium Pipe are in gray metal color with high strength and conductivity. Niobium Tubes /Pipes are used in steel, ceramics, electronics, nuclear energy, and superconductors.
Many of our customers are labs or universities which use niobium tubing for its excellent superconducting properties. We can supply product in commercial grade, reactor grade and even RRR300 for advanced technology applications such as supercolliders.The industry standard specification for niobium tube is ASTM B394 R04210 for commercial grade and ASTM B394 R04200 for reactor grade niobium tubing.

Niobium Tube Standard
All niobium and niobium alloys tube products follow standard ASTM B394, such as pure niobium tubes (R04200, R04210), Nb1Zr tube (R04251 R04261), Nb10Zr , C-103, Cb-752, C129Y, FS-85, Nb-50Ti and so on.
Niobium Tube Technology
- One of the niobium tubes extrusion production method includes the following steps: preparation, a power frequency induction heating (600 + 10˚C), glass powder lubrication, secondary power frequency induction heating (1150 + 10˚C), reaming (reduction of area is not greater than 20.0%), thrid power frequency induction heating (1200 + 10˚C), small deformation, extrusion, extrusion ratio is not more than 10, reduction of area is not greater than 90%) and air cooling technology, finally the hot extrusion process of niobium tubes is finished.
- The niobium seamless tube produced by this method ensures sufficient thermal process plasticity. The disadvantage of niobium fluidity is avoided by means of small deformation extrusion. Performance and dimensions meet user requirements.
Applications
Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties, it resembles tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, halogens, nitrogen, and sulfur. The metal is inert to acids, even to aqua regia at room temperatures, but is attacked by hot, concentrated acids, and especially by alkalis and oxidizing agents.
Niobium Tubes and Niobium Pipe are used in steel, ceramics, electronics, nuclear energy, and superconductors.
Niobium Capillary Tube and Niobium Zirconium Capillary Tube are often used in high pressure sodium lamp production.
