Niobium wire is drawing and 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.

 

 

We are trying our best to innovate our techniques, enhance the product quality, increase the product utilization rate, lower down the costs, improve our service to supply our customers’ with higher quality products but lower purchase costs. Once you choose us, you will obtain our stable high quality products, more competitive price than other suppliers and our timely, high efficient services.
