Niobium

Niobium is a shiny, white, soft, ductile and paramagnetic metal, which takes on a bluish tinge when exposed to air at room temperatures for extended periods.  It has a low density in comparison to other refractory metals, and it is corrosion resistant, exhibits superconductivity properties, and forms dielectric oxide layers. These properties, especially the superconductivity, are strongly dependent on the purity of the niobium metal. When very pure, it is comparatively soft and ductile, but impurities make it harder.

Varnl specializes in manufacturing high performance Niobium and its alloys for a good variety of customers and markets worldwide, available in diversified fabricated forms including sheet, foil, rod, wire,tube and etc.
