Recycling

OxideMolymet (Chile) is the world's largest processor of molybdenum ore concentrates and our main supplier of molybdenum trioxide. The Plansee Group holds a 21.15% share in Molymet. Global Tungsten & Powders (USA) is a division of the Plansee Group and our main supplier of tungsten metal powder.

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.

Our materials

We at Plansee Composite Materials 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 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
