    Production and manufacturing process

    Everything from a single source – from the powder to the final product

    We do everything ourselves when it comes to the production and processing of our composites. From raw material to the final product, including research and development: we combine all of our technological expertise to guarantee quality at the highest level.

    OxidMolymet (Chile) ist der weltweit größte Verarbeiter von Molybdän-Erzkonzentraten und unser Hauptlieferant für Molybdäntrioxid. Die Plansee Group hält 21,15 % Anteile an Molymet. Global Tungsten & Powders (USA) ist eine Division der Plansee Group und unser Hauptlieferant für Wolfram-Metallpulver.

    Our manufacturing process

    With the careful mixing of our special metal powders, we lay the foundation for our unbeatable products. Depending on product requirements, we compress the powder to produce formed parts by means of various procedures, such as die pressing with mechanical or hydraulic pressure application. We manufacture our green compacts for semifinished product blanks by means of cold isostatic hose crimping. We use hot pressing to manufacture a dense, binder-free semifinished product in a single production step. We achieve the optimum density by means of subsequent sintering or liquid phase sintering. Some composites are produced at Plansee Composite Materials by means of special procedures such as infiltration and back-casting.

    At Plansee Composite Materials we specialize in tungsten-based composites, so-called W-based Metal Matrix Composites (W-MMC), 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 advantages of our materials at a glance

    • 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

    Further details regarding these special properties can be found in the materials area:
