ASTM B708 Tantalum Sputtering Target , Rectangular Targets , Ta 99.95%-99.99% Purity




Tantalum sputtering target is mainly applied in semiconductor industry and optical coating industry. We manufacture various specifications of tantalum sputtering targets upon the request of customers. Through vacuum EB furnace smelting method, we get high purity tantalulm ingots range from 99.95% to 99.99%Ta content or even higher which is depend on customs' needs. By wary of unique rolling process, through complicated treatment and accurate annealing temperature and time, we produce different dimensions of the tantalum rectangular sputtering targets. Moreover, we guarantee the grain size is below 100um, flatness is below 0.2mm and the Surface Roughness is below Ra.1.6μm.And the tolarance are controlled as ASTM standard.


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 each lot.




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.
