Niobium Tube Description

Niobium Tube and Niobium Pipe are in gray metal color with high strength and conductivity. Niobium Tubes/Pipes are used in steel, ceramics, electronics, nuclear energy, and superconductors.

Many of our customers are labs or universities which use niobium tubing for its excellent superconducting properties. We can supply product in commercial grade, reactor grade and even RRR300 for advanced technology applications such as supercolliders.

The industry standard specification for niobium tube is ASTM B394 R04210 for commercial grade and ASTM B394 R04200 for reactor grade niobium tubing.
