Niobium sheet Nb element 41 99.99% niobium strip sheets selectable cut to size 100 - 750mm

Niobium is a light grey, shiny metal with good cold formability and high heat resistance. It is often used as an alloying element. You can find the most important metals at favourable prices in our Auremo online shop.

Niobium is very similar to tantalum and has similar properties. It has excellent chemical resistance and high heat resistance as well as a high melting and boiling point. It also has good cold formability.

Due to its good cold ductility, niobium can be formed very well without cutting, but the formation of flow chips makes machining more difficult. Due to its metallic properties, niobium is well suited for welding and soldering.

Niobium is often used as an alloying metal for steel in order to improve the heat resistance, wear resistance and weldability of the steel alloy. One special property is its superconductivity, which is used in nuclear and reactor technology. Niobium is alloyed with tin, aluminium and zirconium for this purpose. At high temperatures, this alloy loses its electrical resistance and enables the loss-free transmission of electrical energy.
