Niobium Bar, Niobium Rod
Niobium bars and rods are cylindrical products made of pure niobium metal or niobium alloys. They are commonly used in the aerospace, nuclear, and semiconductor industries for their unique properties, such as high melting point, excellent corrosion resistance, and superconductivity. The niobium bars and rods are available in various sizes and lengths, and they can be machined or fabricated to meet specific requirements. They are often used in applications such as furnace components, chemical processing equipment, and electrical contacts.

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.
