Our founder has more than twenty years' experience in tantalum and niobium and its alloy smelting and deep processing. He had been working for Ningxia Orient Tantalum Industial Co., Ltd as factory director for almost 20 years. And our main technican are all come from Ningxia Orient Tantalum Industial Co., Ltd with very proficient skills.
We have entered a long term contract with Chinese biggest wet process plant to gurantee us stable and high quality conflict free tantalum and niobium raw materials.
We owns 800KW High Vaccum EB Furnace which can produce niobium ingots as big as 300mm diameter.
Our niobium tubes has passed ISO9001. We analyze niobium ingots in Northwest Institute for Non-ferrous Metal Research and Baitai Group Analysis Center.
Besides niobium tubes, we also produce tantalum and niobium ingots, plates, sheets, strips, foils, rods, wires, sputtering targets. Welcome to contact us to get more information.
