Principal Design Features
|
|
Niobium (also occasionally called Columbium) is a relatively light metal that maintains high mechanical properties at extreme temperatures. Niobium is extremely similar in many ways to Tantalum. They were discovered almost simultaneously and many metallur

Applications
|
|
The largest user of niobium was and is the nuclear power industry, however the alloy has successfully been employed in a variety of other applications including jet engine components. It is commonly used as an alloying element in many of the high temperat
|
|
|
Machinability
|
|
In general, niobium has a strong tendency to gall.
|
|
|
Forming
|
|
Niobium, because of its low work hardening rate can readily be formed and stamped, although great care must be taken with lubrication.
|
|
|
Corrosion Resistance
|
|
Niobium is resistant to most common acids at even high concentrations below 100 C, with the exception of hydrofluoric acid.
|
|
|
Welding
|
|
TIG welding is the preferred method for niobium, with a few notable modifications. The weld pool must be covered with inert gas both on the face and back of the weld area.
|
|
|
Forging
|
|
Niobium can be cold forged from ingot at room temperature.
|
|
|
Cold Working
|
|
Niobium possesses excellent cold working properties and can be forged rolled or swaged from ingot at room temperature.
|
|
|
Annealing
|
|
Heat thoroughly at 1200 C in inert gas or vacuum at pressure below 1 x 10 -4 Torr.
