We manufacture various specifications of niobium sputtering targets upon the request of customers through vacuum EB furnace smelting method. By way of cold rolling process, through complicated treatment and accurate annealing temperature and time, we produce high quality niobium rolling material for disc sputtering targets deep processing.


Moreover, we guarantee the niobium purity is higher than Nb 99.95%; the grain size is below 30-80um, which also can be customized as per request of customers, 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 perfect products.


Niobium sputtering 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 for energy-saving glasses, information storage, solar cell, chemical corrosive environment and shipping enterprise.



We are also glad to provide you the trade in service. We can recover your used sputtering targets to help you with supplying a same new one with lowest price.
