1-5ml niobium tube

I. Product Overview Nickel seamless tube are seamless non-ferrous metal tubes made from metallic niobium (Nb) or niobium alloys through smelting, forging, extrusion, cold rolling/cold drawing, heat treatment, and finishing. They possess excellent corrosion resistance, high temperature resistance, low neutron absorption cross section, good low-temperature superconductivity, and weldability, making them critical corrosion-resistant/structural tubes for extreme working conditions.
