    Tungsten Heavy Alloy
  • Description

    Tungsten heavy alloy is major with Tungsten content 85%-97%, and add with Ni, Fe, Cu, Co, Mo, Cr materials. The density is between 16.8-18.8 g/cm³. Our products are mainly divide into 2 series: W-Ni-Fe, W-Ni-Co (magnetic) and W-Ni-Cu (non-magnetic). AEM can produce various big-size Tungsten heavy alloy parts by CIP, various small parts by mold pressing, extruding or MIN, various high-strength plates, bars and shafts by forging, rolling, or hot extruding. According to customer’s drawing, we can also produce various shape, design technology process, develop various products and later machine.
