XOT metals provide niobium rolling products, including niobium sheet,niobium plate (board), niobium foil,niobium strip & and ribbon.
Niobium is a chemical element with the symbol Nb and atomic number 41. It is a soft, grey, ductile transition metal. It has physical and chemical properties similar to the element tantalum, and the two are therefore difficult to distinguish.
Nb is used in various superconducting materials. These superconducting alloys, also containing titanium and tin, are widely used in the superconducting magnets of MRI scanners. Other applications of Nb include welding, nuclear industries, electronics, optics, numismatics, and jewelry. In the last two applications, the low toxicity and iridescence produced by anodization are highly desired properties.

Production method
XOT produce niobium sheet by vacuum electron beam melting technology.
First, melt the not forging niobium bar into niobium ingot by vacuum electron beam melting technology. There are two ways of smelting, single smelting and multiple smelting. Usually we smelt two times, or it can be more than two times depending on the product specific requirements.
Second, forging and axial breakdown niobium ingot and make it into niobium slab, then take it for annealing treatment and cleaning. After several times of rolling and annealing finally get the high quality niobium sheet. The unique way of rolling and annealing, temperature and time control that Giant Metal have guarantees the excellent quality.
