Description

 

Niobium tubes are manufactured by ASTM B391 niobium ingots through annealing, cold rolling, cold drawing technology. 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% up, which will be smelted again in high Vacuum EB furnace to be purified and produce Niobium ingots with purity 99.9% 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.

 

We produce R04200, R04210 seamless tubes/pipes, welding tubes/pipes, capillary tubes which meet ASTM B 394-98 standard and the sizes can be customized as per your required dimensions.
