Industry knowledge

Niobium, a superconductive material, it is used in applications such as jet engines,particle accelerators, nuclear reactors and medical applications.


Niobium, also termed Columbium, is a shiny grey metal that takes on a bluish tinge when exposed to air at room temperature. Due to its low capture cross section for thermal neutrons, Niobium has application in the nuclear industry. Niobium can be electrically heated and anodized to a wide variety of colors that makes it very attractive in the jewelry industry. Niobium is added to iron or nickel to produce alloys in the aerospace, medical and electronics industries.

Available Niobium FoilNiobium Foil (cold rolled, annealed) Thickness: minimum 0.025 mm (25 μm) Width and length: 500 mm or cut to size Standard: ASTM B393 UNS R04200 Reactor grade unalloyed niobium UNS R04210 Commercial grade unalloyed niobium UNS R04251 Reactor grade Niobium-1% zirconium UNS R04261 Commercial grade Niobium-1% zirconium Alloying niobium with 1% zirconium increases the strength of niobium, and decreases slightly its elongation. The increased strength is very advantageous especially at temperatures above 600 °C
