Niobium strip is niobium flat products but can be rolled to supply with width < 6inch(152.4mm), thickness is between 0.005inch (0.13mm) and 0.1875inch (4.76mm). It is corrosion resistant. Its melting point is 2468℃ and boiling point 4742℃. It is has the largest magnetic penetration than any other elements and it also has superconductive properties, and a low capture cross section for thermal neutrons. These unique physical properties make it useful in super alloys used in the steel, aerospace, shipbuilding, nuclear, electronics, and medical industries.


We produce R04200, R04210 plates, sheets, strips and foils which meet ASTM B 393-05 standard and the sizes can be customized as per your required dimensions. We will do our best to fulfill customers' needs and markets' demands by providing a great variety of customized products. Taking advantages of our high quality niobium oxide raw material, advanced equipment, innovative technology, professional team, we tailored your required products. You may tell us all your requirements and we dedicated in manufacturing upon your needs.



More than 20 years’ experiences in tantalum / niobium and its alloy smelting and deep processing, we make sure that we can provide you with the best quality products with competitive price. We have entered a long-term contract with the Chinese biggest tantalum/niobium hydrometallurgy smelter to assure our stable and high quality raw material. The full and strict quality control system throughout the whole production line from the raw material till the products ready for delivery, we reject the unqualified products timely to make sure only qualified products can be received by our customers.


Application: Mechanical stamping for Nb shells, containers etc. Used for chemical anticorrosion, capacitor parts, target material for optics industry, superconducting material, electrical light material, medical treatment, refrigeration, artificial diamond and alloy addition
