Our Strength:


More than 20 years’ experiences in tantalum /niobium and its alloy smelting and deep processing, we make sure that we can provide you with the best quality products but lowest price among the niobium sputtering targets suppliers.


We are doing our best to control a good quality and cut down our costs. For example,we have entered a long-term contract cooperation with the Chinese biggest tantalum/niobium hydrometallurgy smelter to assure our stable and high quality raw material. We have purchased the new advanced Vacuum EB furnace to product the high purity tantalum ingot and we also equipped with high vacuum Annealing Furnace, plate and strip rolling mill, High precision surface grinding machine etc. The full and strict quality control system throughout the whole production line from the raw material till the products ready for delivery, we reject the unqualified products timely to make sure only qualified products can be received by our customers.
