More Information

Our niobium bars and rods are used in a vast array of applications. Some of these uses include sodium vapor lamps, HD television backlighting, capacitors, jewelry and chemical processing equipment. Our manufacturing process uses cold rolling and annealing to produce bars and rods with ideal mechanical properties and uniform grain structures throughout the rod or bar.

HS Metal’s niobium wire is available in various grades; each custom manufactured to your unique industry requirements.

Niobium rods and Niobium bars are usually used in the production of niobium wire, and can also be used in the production of niobium workpieces. It can be used as the internal structural parts of high-temperature furnaces and accessories in corrosion-resistant chemical equipment.

Niobium Rod Application

Niobium rods and niobium alloy rods are used as structural materials for aero-engines and rocket nozzles, reactor interiors, and cladding materials, and for the production of various corrosion-resistant parts under the corrosion conditions of nitric acid, hydrochloric acid, or sulfuric acid. Adding zirconium to the niobium rod can significantly improve the oxidation resistance and strength of the material.
