One niobium alloy, commonly used in lighting and chemical processing, has 8 names: • NB-1Zr • Niobium-Zirc • Niobium One Zirc • Niobium Zirconium • Niobium - 1 Zirconium • Niobium 1% Zirconium • NB-1%Zr • Niobium 1% Zirc

Niobium, formerly called columbium, melts at 2468° C (4474° F). It is a tough, ductile, silver-gray metal having a unique combination of physical and mechanical properties. Of the five major refractory metals, it has the lowest melting temperature, density (8.57 g/cm3), and elastic modulus at room temperature (103 GPa, or 14.9 x 106), while its coefficient of linear thermal expansion (7.3 m/m - K) is the highest. Niobium is also extremely stable in a wide variety of corrosive environments including most organic acids and mineral acids with the exception of hydrofluoric acid. Major applications are in capacitors, lighting and chemical processing.
