Niobium Tube (Nb tubing)

Email us

We provide niobium seamless tube, welded tube & pipe, and niobium capillary tube. Other niobium tubular products such as niobium ring are also available on request.

Edgetech Industries LLC is a leading global supplier of niobium tubing, we provide custom pipe and pipe sizes at short notice.
In addition to commercially pure niobium, Edgetech also provides reactor-grade niobium, niobium-zirconium alloys, niobium-hafnium alloys, niobium-tungsten alloys and niobium-titanium alloys.
Niobium is typically supplied to meet ASTM B392, ASTM B393, ASTM B394, AMS 7850, ASTM B654, ASTM B655, R04200 Type 1, R04210 Type 2, R04251 3 Type, R04261 Type 4, C129Y, FS-85.

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.

Specifications for our Niobium tube and pipe
Specifications: ASTM B394
Material Grade: R04200, R04210
Purity: 99.9% Niobium

Our seamless pipes are directly rolled, while welded pipes are made by welding niobium sheets or strips. The thickness of the sheets is the wall thickness of the pipe. The two processes can be determined according to the custome’s own needs and product size. Generally speaking, welding is suitable for pipes with larger outer diameters and thinner walls.

Characteristics and Applications of Niobium Tubes
-Aerospace: Niobium’s high melting point and corrosion resistance make it suitable for high-temperature applications such as jet engine parts, rocket nozzles, and turbine blades.
-Medical devices: Due to its biocompatibility, niobium is used to make medical implants, including pacemaker housings, bone screws, and artificial joints.
-Chemical Equipment: Niobium’s corrosion resistance makes it ideal for chemical processing equipment and piping systems, especially in environments that handle strong acids, strong bases, and other corrosive chemicals.
-Nuclear Industry: Niobium’s low thermal neutron capture cross section and high heat resistance make it useful as a structural material and fuel cladding for nuclear reactors.
-Superconducting Technology: Niobium exhibits superconducting properties at low temperatures, making it an essential material for key components in superconducting magnets, superconducting cables, and particle accelerators.
-Electronics Industry: Niobium has excellent electrical conductivity and stability and is used to make electronic components such as capacitors and electrodes.
-High-temperature Furnaces: Niobium tubes are used for heating elements and protective sleeves in high-temperature furnaces because they maintain stable physical and chemical properties in extremely hot environments.
