Niobium Tube

Niobium Tube

Niobium tubes, also known as niobium pipes, are often used as anode leads for capacitors. They characterize high melting point, excellent anti-corrosion property and workability in cold environment.

Niobium tubes are widely used in chemistry, electronics, aviation and aerospace industry. They can be used as material for high pressure sodium lamp, nozzles and structural parts for airplane engines, anti-corrosion parts under strong acid environment in chemical processing industry.

Package and Transportation
We pack niobium pipes in plywood case and send them by ocean or air.
