Compared to pure niobium, the addition of zirconium to niobium-1-zirconium (Nb-1Zr) rods improves the material’s strength and stability at high temperatures, while maintaining good ductility, corrosion resistance, and machinability.
Nb-1Zr rods are suitable for high-temperature, vacuum, aerospace, and specialized engineering applications. They can be used to manufacture various high-temperature structural components and precision parts using turning, milling, grinding, and other machining methods.
ASTM B392 is the applicable standard for bars, rods, and wire made of niobium and niobium alloys, including two Nb-1Zr grades: R04251 Type 3 and R04261 Type 4.
It is used in the manufacture of high-temperature structural components, specialized engine parts, heat-shielding components, and other parts that require high heat resistance.
It can be used to manufacture supports, connectors, and other high-temperature components for vacuum furnaces, high-temperature furnaces, and heat treatment equipment.
Thanks to the excellent corrosion resistance of niobium alloys, they can be used to manufacture components for equipment operating in specific corrosive environments.
Nb-1Zr can also be used in high-temperature experimental equipment, vacuum equipment, research instruments, and custom-made parts manufactured to customer specifications.
