    Premium Tungsten Supplier

    - Your Source for High-Quality Tungsten

    Tungsten is a metal known for its exceptional properties. It has the highest melting point (3422°C), lowest vapor pressure, and highest tensile strength among all metals. It also has a very high density (19.3g/cc), and a high degree of mechanical strength and ductility. These qualities make it a great option for applications that need to withstand high temperatures, remain stable in shape, and have strong mechanical strength.

    AEM Metal is an professional tungsten supplier, we provide a variety of tungsten products, including pure tungsten metals, tungsten heavy alloys, tungsten copper, tungsten silver, and tungsten carbide. Our products are of high quality and competitively priced. If you need custom products, feel free to reach out to us.

    Global Tungsten Resource Reserves

    Global Tungsten Resource Reserves

    Source: USGS

    Tungsten is a rare metal, but it is China's dominant resource species. According to statistics from the United States Geological Survey (USGS), the world's proven tungsten metal resource reserves total 3.8 million tons, of which 1.8 million tons are distributed in China, accounting for about half of the world's total reserves. China's tungsten metal exports account for a larger proportion. In 2022, the world produced a total of about 84,000 tons of tungsten, of which 71,000 tons were produced in China, accounting for about 85%. Therefore, it can be said that the global tungsten metal is mainly dominated by China.

    Producing Tungsten Based on Powder Metallurgy

    W Powder
    Mixing Alloys
    Heat Treatment
    Mechanical Processing
    Quality Assurance

    W Powder: AEM Metal produces and sells high-purity tungsten powder. We use 2-8 um tungsten powder to manufacture pure tungsten products, and we use 2.5-3.5 tungsten powder to manufacture tungsten alloy products.

    Mixing Alloys: AEM Metal could manufacture WNiFe, WNiCu, WRe, AgW, WMo and cemented Tungsten Carbide.

    Pressing: We compress our metal powder and metal powder mixtures into a so-called green compact. For final products with especially difficult geometries, we then press the green compact into the corresponding final shape.

    Sintering: Sintering is the key technological step in powder metallurgy. The green compact is heated in a sintering furnace in a protective gas atmosphere. This makes the powder grains coalesce, resulting in a sinter block with a low porosity.

    Forming: We form the sinter blocks into a highly durable semi-finished product. The density and mechanical strength of our materials increase with an increasing degree of forming.

    Heat Treatment: Using heat treatment, we balance out the mechanical stress, influence the material properties as well as ensure that the metals are easy to process later on.

    Mechanical Processing: AEM Metal could provide turning, milling, grinding, cutting, joining and coating processing steps.

    Quality Assurance: AEM Metal provide Quality Certification per each order.

    Photovoltaic silicon wafers will develop in the direction of "large size" and "thin wafer" in the future. Under the trend of "thinnerization", "fine wire and high speed" are the main development trends of diamond wire. Tungsten wire has the advantages of large thin wire space, high tensile strength, strong breaking force, good toughness, fatigue resistance and corrosion resistance. It will gradually replace high carbon steel wire and become a new generation of diamond cutting wire busbar.
