Niobium is a soft, grey, crystalline, ductile transition metal . Niobium targets are used as coating materials for optics for coating films on the glass. Its melting point is 2468℃ and boiling point 4742℃. It has the characteristics of high temperature resistance, high corrosion resistance and good ductility. Niobium sputtering target(Nb target) is the main raw material of niobium and its alloy film, which are widely used in color TFT, LCD, panel PC, optical lenses, glass coatings, electronic image, advanced touch screen, flat panel display and surface coating material for energy-saving glasses, information storage, solar cell, chemical corrosive environment and shipping enterprise.


e manufacture various specifications of niobium sputtering targets upon the request of customers through vacuum EB furnace smelting method. By way of unique rolling process, through complicated treatment and accurate annealing temperature and time, we produce different dimensions of the tantalum sputtering targets such as disc targets, rectangular targets and rotary targets. Moreover, we guarantee the niobium purity is between Nb 99.95% to 99.99% or higher; the grain size is below 30-80um, flatness is below 0.2mm and the Surface Roughness is below Ra.0.4μm. 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.


We are proficient in niobiuim target process and has supplied our targets to Japan, Germany, Taiwan. We are continously innovating our techniques, enhancing the product quality, increasing the target utilization rate and  lowering down the costs of our customers. We are improving our services to supply our customers with higher quality products but lower purchase costs.




Our Strength:


The founder of Towin Rare Metals and the key technician owns more than 20 years’ experiences in Niobum targets production. We are pursuing to provide our customers with the best quality products and most competitive price.


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 niobium raw material. We have purchased the new advanced Vacuum EB furnace to product the high purity niobiuim ingot and we are 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 final products such as Nb sputtering targets ready for delivery, we reject the unqualified products timely to make sure only qualified products can be received by our customers.


In addition, we offer various kinds of services to our customers such as OEM, forging services, sintering services, laser cutting services, rolling services, milling services, trade in services etc. Please feel free to send us the enquiries as long as you require services.
