The Materials You Need When You Need Them

Niobium Refractory Metals

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 colours 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.

Niobium Products

Ed Fagan Europe Ltd. stocks Niobium Foil/Coil in a variety of sizes. Below are some of the standard stock items. If you require other forms of Niobium, please call one of our materials experts; our sales people are very knowledgeable and can assist you. We can cut, slit, shear, or center less grind Niobium to your exact specifications, and we also have tremendous versatility when it comes to custom sizes, packages, and unusual materials.
