Tungsten Heavy Alloy Electrodes
ungsten Heavy Alloys are materials with a high tungsten content and low amounts of Ni,Fe or Ni,Cu. Some tungsten alloy is added Mo etc.Their densities could be as high as 16.8-18.8g/cc.XYXC offers two kinds of tungsten heavy alloys:W-Ni-Fe(magnetic)and W-Ni-Cu(nonmagnetic). Large size of tungsten parts are produced by CIP, various of small parts are produced by mold pressing,extruding or MIM. XYXC can also produce high strength bars,shafts and thin sheets by forging and rolling.
Product Standard:
ASTM B777-07
Applications:
Used as electrodes for resistance welding.
