Niobium Tube / Pipe

niobium tube

Niobium Tube / Pipe processing technology

It usually takes two times of extrusions in the processing of Niobium Tube / Pipe. After the first extrusion, the plasticity of Niobium alloy was significantly improved. Especially after recrystallization annealing, not only the second extrusion can be carried out, but also other pressure processing can be carried out at a lower temperature.

Application of Niobium Tube / Pipe

Niobium and Niobium alloy tubes have the characteristics of high melting point, good corrosion resistance, cold working performance. They are widely applied in chemical industry, electronics industry, aviation and aerospace industry, mainly used in the production of high pressure sodium lamp, aviation and aerospace engine structure material, chemistry reaction vessel, heat exchanger tube, reactor internal components and coating materials. Adding Zirconium into Niobium can significantly improve the oxidation resistance and strength of the material.
