    Purity: W>99.95% (99.98% can also be achieved if special demanded)
    Density: >18.3g/cm3
    Surface: sintering surface, forged surface, ground surface, polished surface
    Tungsten rod features high hardness, low mechanical abrasion with smooth surface. Moreover, it is characterized by high temperature resistance and high creep resistance.

    Tungsten Rod Applications

    Tungsten bars are mainly used for cathode radiation rods and high temperature forming tungsten rods, which can be used as the auxiliary wire, leading-in wire, printer needle and various quartz heating furnaces.

    Surface Condition of Tungsten Rod

    Black Surface – Surface is “as swaged” or “as drawn”; retaining a coating of processing lubricants and oxides.
    Cleaned Surface – Surface is chemically cleaned to remove all lubricants and oxides.
    Ground Surface – Surface is center-less ground to remove all coating and to achieve precise diameter control.
