ApplicationAfter rolling and processing with deflection reaching 60% , the density of tungsten sheet basically comes close to tungsten’s theory density. Therefore, tungsten sheet possesses the properties of high density, balanced internal structure and excellent high creep strength temperature. tungsten sheet is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats.Package DetailsFirst, packaging with moisture-proof paperSecond, packaging with kraft paperThird, packaging with foam plastics in all side of plywood case.Finally packing products in plywood case TransportationShipping goods by TNT,DHL,Fedex,UPS,EMS etc. Transport goods to Beijing or Shanghai air port by air transportation
