  • Tungsten Heavy Alloy

    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.

    Tungsten Heavy Alloy Applications

    • Military equipments
    • Balance weight for submarine and vehicle
    • Aircraft components
    • Nuclear and medical shields
    • Fishing an sport tackles
