Niobium Materials
Niobium materials are refractory-metal mill products — sheet, rod, wire and tube — supplied per ASTM B393, ASTM B394, ASTM B392. Niobium combines superconductivity, biocompatibility and acid resistance, serving superconducting magnets, sputtering targets, medical implants and sodium-vapor lamps. We supply niobium alongside titanium through the same Baoji sourcing and inspection route.
