Niobium is a soft, grey, crystalline, ductile transition metal which has a very high melting point and 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.
Ingots are generally the least costly metallic form and useful in general applications. Our standard Ingot size is nominallyφ290mm, φ210mm, φ150mm. And we also produce Niobium as rod, wire, plate, sheet, tube, disc, sputtering targets, machined parts and other shapes are available by request.
We smelt the high purity Nb2O5 we sourcing from the Chinese biggest hydrometallurgy plant by means of aluminothermic reduction to produce niobium aluminum alloy. Then the niobium aluminum alloy will be smelted in high Vacuum EB furnace to produce niobium bars with Nb content 99.9% up, which will be smelted again in high Vacuum EB furnace to be purified and produce Niobium ingots with purity 99.95% up. The size can be tailored by the customers’ requirements. We control our products quality through the raw material source till the whole production line and finally deliver to our customers in order to make sure you purchase our products with stable and same quality for each lot. Our QC control our products quality through the raw material source till the whole production line and finally deliver to our customers in order to make sure you purchase our products with stable and same quality for each lot. They use Metallographic microscope, Hand-held X ray Fluorescence, Electronic tensile testing machine etc., instruments to inspect the material and products and issue the COA for each lot. We have been certified by ISO9001:2015.
