Niobium-Zirconium Products | Refractory Metal
Niobium Zirconium Alloy
Niobium-zirconium alloy (Nb-1Zr) combining the superconducting properties of niobium with the enhanced strength and corrosion resistance of zirconium. Available as rod, wire, sheet, tube, and machined parts. Nb-1Zr is the standard alloy for nuclear reactor applications due to its low neutron absorption, excellent corrosion resistance in liquid metals, and good high-temperature strength. Also used in superconducting magnets, chemical processing, and aerospace applications. UNS R04261, ASTM B392 compliant.
