Description
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.
Niobium bars are used in synthetic diamonds, superconductor, high temperature vacuum furnaces, sodium vapor lamps and nuclear reactors. It can also be used for steel making. Its surface should be smooth, clean, greaseless, without fissure or burr, no continuous pitches or scratches
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 and tensile test to inspect the material and products and issue the COA for each lot. We have been certified by ISO9001:2015.
Application: widesly used in synthetic diamonds, superconductor, high temperature vacuum furnaces, sodium vapor lamps and nuclear reactors. It can also be used for steel making.
