Plansee Tungsten Alloys

Plansee Tungsten Alloys is the first choice for tungsten-based composites and alloys (W-based Metal Matrix Composites/W-MMC). The custom-designed components made of heavy metal are particularly dense, corrosion-resistant, and mechanically workable.

Our core competences at Plansee Tungsten Alloys:

  • From the raw material to the ready-to-install component
  • Top product quality from a single source for the most stringent requirements
  • Development and optimization of alloys in a state-of-the-art research laboratory by a dedicated development team
  • Densimet®, Inermet®, and Denal® tungsten composites
  • Sparkal® tungsten-copper composite
  • Highest quality tungsten alloys

    Everything from a single source

    From powder to the final product

    We do everything ourselves when it comes to the production and processing of our composites. The production of our unbeatable products begins with mixing the high-quality powders. Depending on the product application, we use optimized pressing technologies such as CIP or drybag pressing and compress our material by means of subsequent sintering or liquid phase sintering. We manufacture our tungsten-copper composites by means of infiltration. In the case of special product requirements, we forge our materials to ensure maximum strength. Further processing and the manufacture of complex components are also no problem at all. We produce your individual components in sizes of up to 1,200 mm in length and 420 mm in diameter. Our tried-and-tested quality management system enables process monitoring, product tracking, and continuous improvement.

    Material and product properties

    Our materials

    We at Plansee Tungsten Alloys specialize in tungsten-based composites, so-called W-based Metal Matrix Composites, which have particularly special properties:

    • Our Densimet® and Inermet® tungsten composites have a particularly high density (17.0 to 18.8 g/cm3) and reliably shield X-rays and gamma rays. They are not susceptible to expansion in the presence of heat and are particularly good at dissipating heat. As mold inserts for aluminum foundries, they can be repeatedly heated and cooled without becoming brittle. They are also used as balancing weights.
    • The tungsten composite Denal® is particularly strong and impresses with its high tensile strength with sufficient expansion.
    • Our tungsten-copper composite Sparkal® is used in applications in which copper and graphite reach their limits. Wear-resistant tungsten-copper electrodes can even be used to machine carbide without any problems.

    The advantages of our materials at a glance

    From the ore powder to the final product
    • High density of 17.0 to 18.8 g/cm3 (similar to pure tungsten)
    • Better workability than pure tungsten
    • Cost-efficient manufacture of complex products and components
    • High modulus of elasticity, very good mechanical properties
    • High absorption capacity for X-rays and gamma rays
    • Safe for human health and the environment
    • High wear resistance
    • Good thermal conductivity
