Description

 

ANiobium 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.

 

Niobium rod is worked cold from ingot to final diameter. Forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size. We produce niobium bar, rod, wire which are mainly used for producing special steel, high-temperature alloy, magnetic materials and other Nb-bearing alloy. And we also produce Niobium as rod, wire, plate, sheet, tube, disc, sputtering targets, machined parts and other shapes are available by request.

 

Rod is normally supplied with a forged surface above 1-3/8" diameter, and a swaged or drawn finish in smaller diameters. Rod, preferably un-annealed, may be centerless ground to improve diameter tolerances. The minimum diameter for centerless grinding is .125". Rod to a maximum of 1/4" and wire may be supplied in coils or straightened and cut to length.

 

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.
