Tungsten bar is divided into sintered,forged and spinning forged according to processing,while black,lathe-polishing and polishing according to its surface.Since the melting point of tungsten is high,the forging tungsten stick of high purity,high density and outstanding high-temperature creep resistance is extensively applied in making supporting tungsten crucible of sapphire growth furnace,electrode  of rare earth high-temperture furnace,heting parts,connecting parts and supporting stick.While the tungsten rod is uesd in making heating parts,motor contacor and electrode of high-power lamps whose processing methods include sintering,forging,turning forging and polishing.
