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.

We can supply various niobium and its alloy products with different standards, shapes, and compositions as the below:

Niobium plate sheet             Niobium foil strip
Niobium rod bar                   Niobium wire
Niobium tube pipe               Niobium disc ring
Niobium crucible                 Niobium nut bolt
Niobium sputtering target
