 Niobium (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.

Nb Flat Sheet
|
|
|
Our niobium is custom processed for us, annealed and straightened. Each piece is hand inspected, rolled to a 10 micron finish. Maximum 6 x 24 inches. Minimum 3 x 3 inches, larger in 3 inch increments only. Other thicknesses and dimensions are available by special order.

Nb Coiled Strip (annealed)
|
|
|
This is our standard niobium in coil form with an "as rolled" finish.
The surface finish will vary slightly and will have a slight curve from
coiling. Minimum 3 x 3 inches, larger in 3 inch increments only. Other
thicknesses and dimensions are available by special order.

Understanding Anodizing
|
| Anodizing is a fast & simple electrical process that grows very thin transparent oxides on the surface of the reactive metals niobium & titanium. This film generates interference colors similar to the ones you see on an oily wet street. There are no pigments or dyes. It takes a special high voltage electrical power supply (See our Mini Anodizer Section). The process can be applied in a bath or with brushes and other applicators. Colors can be controlled and laid down individually by using masking techniques. |
