General Information on FT Metals’ Niobium Foils and Strips

We offer a wide range of niobium foils (niobium strips), which are highly praised by customers for their good gloss, ductility, high conductivity, and high quality.

Our niobium strips and foils are made by cold rolling of niobium plates. In terms of processing technology, we always carry out appropriate vacuum annealing to improve the deformability of the strip and ensure that the niobium foil can be further stretched, bent, or stamped.
