niobium jewelry wireNiobium (Nb) is named after Niobe, daughter of Tantalus. Ore reserves are found in Canada, Brazil, Nigeria, Zaire and Russia. Nb is used in pure and alloyed form in superconductors, sodium vapor lamps (street lights), rocket boosters and other aerospace applications.
Niobium is so slow to work harden annealing is not necessary for most applications. (Annealing requires a high vacuum or an inert atmosphere furnace.) The reactive metals cannot be soldered and must be joined with cold techniques, i.e. rivets, nuts & bolts, or special settings. Findings can be fusion welded with Sparkie welders. Highly formable, very colorable via anodizing, this is the most popular of the reactive metals.
