Niobium is a soft, grey, crystalline, ductile transition metal which is used in various superconducting materials. Its melting point is 2468℃ and boiling point 4742℃. It has the characteristics of high temperature resistance, high corrosion resistance and good ductility. Therefore, niobium and its alloy are widely used in electronics, iron and steel industry, chemical, jewelry, superconducting, engineering, aviation, aerospace industry etc.


We produce niobium rod, wire, capillary, tube, plate, sheet, strip, foil, sputtering targets etc. We customized the products for our clients based on the demand and drawings. Welcome to inquire us for more information.
