Product Introduction
Our niobium sheets are cold rolled and vacuum annealed with proprietary reduction rates to ensure ideal metallurgy. Each sheet undergoes a stringent inspection for dimensions, surface finish, and flatness.
Niobium sheet is the lightest refractory metal (density 8.57 g/cc) and has a high melting temperature (2,468ºC). This property allows its alloys to provide structural solutions at high temperatures: higher than 600ºC in nickel based alloys and as high as 1,300ºC in niobium based alloys.
Niobium sheet has physical and chemical properties similar to those of the element tantalum. It resists corrosion as it forms dielectric oxide film. The metal starts to oxidize rapidly in air at 200 ºC. Below -264ºC, niobium exhibits superconducting properties. It conducts high densities of electrical current resistance-free, creating magnetic fields and forces that yield important practical applications in medical diagnostics, materials research and transportation.
