Standard size: Diameter 4~100 mm
Purity: Nb>99.95% or >99.99%
Niobium Bar Applications
With a high melting point, excellent anti-corrosion property, and workability in a cold environment, Nb, Nb alloy tube, rod, and wire are widely used in chemistry, electronics, aviation, and aerospace industry. They can be applied as nozzles, structural parts for airplane engines, inside elements, protection material for the nuclear reactor, anti-corrosion parts under strong acid, or environment. Your special requests are welcomed.
