  • Fine Tungsten Powder

    The high quality and high purity fine tungsten powder are typically greater than 99.95% tungsten purity with average particle sizes up to 10 microns. These powders are used in powder metallurgy applications such as electrical contacts, heavy metal alloys, electronic heat sinks, mining tools and fabricated tungsten rod/bar.

    Analytical Report
    A Certificate of Analysis (COA) accompanies each shipment of tungsten carbide powder. We prepare each COA to include the following:
    • Average Particle Size (Fisher Sub-Sieve ASTM B-330)
    • Apparent Density (Scott Volumeter ASTM B-329) ]
    • Particle Size Distribution (Photelometer ASTM B-430, Sedigraph, or Malvern Mastersizer)
    • Chemical Impurity Analysis

    Packing:In iron drums lined with double plastic bags of 50 or 100 kgs net each.
    Note:Any particular requirements to the products can be discussed.

    If you have any interest in tungsten powder, please feel free to contact us by email: sales@chinatungsten.com or by telephone: +86 592 5129696.
