About Niobium

Niobium is a naturally occurring element. It is a metal that is ductile, malleable and highly resistant to corrosion. Because it enhances properties and functionalities, niobium is used in a wide range of materials and applications in the Mobility, Structural and Energy sectors. Niobium transforms materials. When added to materials like steel, glass and aluminum castings, niobium makes them more efficient and lowers environmental impacts, while also increased value.

About Tantalum

One of the main uses of tantalum is in the production of electronic components. Tantalum (Ta) causes no immune response in mammals, so has found wide use in the making of surgical implants. It can replace bone, for example, in skull plates; as foil or wire, it connects torn nerves; as woven gauze it binds abdominal muscle. Tantalum alloys can be extremely strong and have been used for turbine blades, rocket nozzles and internal combustion engines.
