Niobium and niobium alloy rod-bar are widely used in chemistry, electronics, aerospace, and other fields due to their advantages of high melting point, corrosion resistance, and cold processing.

Our niobium bars are widely used in various fields. Including sodium vapor lamps, high-definition TV backlights, capacitors, jewelry, and chemical processing equipment. We use cold rolling and annealing manufacturing processes to produce niobium rods and wires with ideal mechanical properties and uniform grain structure. TFM’s niobium rods are available in various grades; each customization is made according to your unique industry requirements.

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