Niobium (Nb) Metal

Niobium (Nb), also referred to as Columbium, is a silvery metal that is very resistant to corrosion due to a layer of oxide on its surface. It has superconductive properties and is comparatively soft and ductile when very pure.
Niobium improves strength when used in alloying.
99.8% up to 99.99%
Typical Applications

Niobium’s main use is to increase the strength of alloys, particularly at low temperatures. It is used in stainless steel, alloys in jet engines and rockets, beams, girders for buildings and oil rigs, and oil and gas pipelines. It is also used in superconducting magnets for particle accelerators, MRI scanners, and NMR equipment.
Niobium and some of its alloys are physiologically inert and hypoallergenic and are used in medical devices and jewelry.
