The Cas No. of Nb strip is 7440-03-1.
Niobium Foil has good corrosion resistance and is stable in a variety of chemical environments. Nb Strip is a superconductor, and Niobium Cb Foil can exhibit superconductivity at low temperatures, so it has a wide range of applications in superconducting technology.
Niobium has a high melting point, which allows Columbium Foil to remain stable at high temperatures.
Pure Niobium Strip can be machined into a variety of shapes and sizes for different process needs.

Niobium foil is usually deep drawn to niobium cup. So it plays important roles in deep draw application. In superconducting applications, Niobium Foil is often used in superconducting devices such as superconducting cables, superconducting magnets, and superconducting quantum interferometers. Nb Strip is often used as a vacuum evaporation material for the preparation of films and coatings because of its high melting point and good corrosion resistance. Columbium Cb Strip can also be used to manufacture semiconductor devices, components in the aerospace sector, corrosion resistant parts for chemical equipment, and medical applications. Niobium strips can also be used in jewelry industry to make the colourful niobium strip. Bright surface finishing Nb foil is the common raw materials for jewelry industry.
In addition to Niobium Foil, we also produce Niobium Tube & Pipe, Niobium Sheet & Plate, Niobium Ingot, Niobium Pellets, Niobium Strip, Niobium Rod, Niobium Wire, Niobium Disc, Niobium Shield, Niobium Target, Niobium machined parts, Niobium Spherical Powder. They meet Standard ASTM B 394 R04200, ASTM B 394 R04210, ASTM B 393 R04200, ASTM B 393 R04210, ASTM B 392 R04200, ASTM B 392 R04210, ASTM B 391 R04200, ASTM B 391 R04210.
