Production equipments

four-high cold mill, vacuum annealing furnace, W43G series straightener, hydraulic plate shears, water jet, wire cutting machine, flat-stone mill

Applications of Tungsten Sheet

Since the melting point of tungsten has reached 3380oC, 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 furnacesputtering target applied in plasma coating film, and high temperature resistance boat.
