    Tungsten heavy alloy is mainly made up of tungsten, with a tungsten content ranging from 85% to 97%. It is strengthened by adding materials like Ni, Fe, Cu, Co, Mo, and Cr. This alloy has a density between 16.8 and 18.8 g/cm³.

    At AEM, we have two series of products: WNiFe, WNiCo (magnetic), and WNiCu (non-magnetic). We manufacture large tungsten heavy alloy parts using CIP, while small parts are made through mold pressing, extruding, or MIN. We also offer a wide range of high-strength plates, bars, and shafts produced by forging, rolling, or hot extruding.

    We can create different shapes based on customer drawings, provide design technology processes, and develop various products. Additionally, we offer post-machining services to meet our customers' needs.

    Applications of Tungsten Heavy Alloy  (WNiFe, WNiCu, WNiCo) 

    • Military equipment
    • Balance weight for submarine and vehicle
    • Aircraft components
    • Nuclear and medical shields (military shield)
