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 produce R04200, R04210 targets which meet ASTM B392, ASTM B393 standard and the sizes can be customized as per your provided drawings or dimensions.


We 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 will do our best to fulfill customers' needs and markets' demands by providing a great variety of customized products. Taking advantages of our high quality tantalum ingots, advanced equipment, innovative technology, professional team, we tailored your required sputtering targets. You may tell us all your requirements and we dedicated in manufacturing upon your needs. We have been certified by ISO9001:2015.


If you require customization service, you only need to send us your required material, purity, dimension, quantity or a drawing for an inquiry. We will reply you our best quote ASAP.
