Exotech Buys and Sells Niobium
Niobium (Nb), aka Columbium, is Tantalum’s big sister. In nature, Niobium exists as a complex mineral that contains varying levels of Tantalum. It is not surprising that as pure metals, Niobium and Tantalum have similar chemical and metallurgical properties.
Typically, Niobium is added to HSLA (high strength low alloy) steels, stainless steels, and Nickel based alloys. Ferro Niobium, Nickel Niobium, Niobium Oxide, Pure Niobium and Niobium bearing scrap are used for these additions.
Applications for Niobium and Niobium based alloys include superconducting alloys, rocket nozzles, chemical equipment, medical devices, thin films and electronic components. Oxides and Carbides of Niobium are used in a variety of other applications.
Niobium Purchased by Exotech
Exotech’s development of physical, chemical, and thermal processes for Niobium scrap evolved out of our work with Tantalum scrap. Niobium scrap is processed by Exotech into material that matches the chemical and physical requirements of the alloy additive industry. Thus we can purchase solids, turnings, powders, grindings and residues that contain Niobium.
Niobium Products Supplied by Exotech
Niobium materials produced by Exotech, are used by the vacuum and air melt alloy producers and sold with a known chemistry. Material is certified by both our in-house instrument laboratory (ICP, LECO & XRF) and contracted outside accredited laboratories. Exotech Niobium processed scrap is used by many alloy melting facilities, both in the USA and overseas.
