During the aluminum casting process, the metal melt is either poured or pressed into the mold. This process is used, for example, to manufacture cylinder heads, wheel rims and many other aluminum castings. Here, the mold has to repeatedly withstand the metal melt at a temperature of over 600 °C: for inserts made of our tungsten-heavy metal alloy Densimet® and the molybdenum alloy TZM, that's not a problem. The benefits to you: — Shorter cycle times — Top surface quality for your products — Long mold service life — No cracks in the mold insert Tailor-made mold inserts, sprue bushes, cooling inserts and other individual parts as well as semi-finished products for your mold are available.

Plansee charge carreiers from refractory metals are dimensionally stable at high temperatures and in contrast to graphite parts they are also suited for high-vacuum furnaces. MLR with its superior creep resistance and retained ductility after high temperature operations is the ideal material for mechanically loaded furnace parts. Plansee designs and fabricates furnace fixtures to customer specifications, e.g. for aeronautics, glass industry, Metal Injection Molding (MIM), commercial heat treatment and various other thermal processes. Alongside molybdenum and tungsten, we primarily manufacture our charge equipment from TZM and ML. The creep resistance of these alloys is ten times better than that of pure molybdenum and they are also exceptionally ductile. As a result, our charge systems are perfectly equipped to cope with frequent changes between high and low temperatures.

Metallic hot zones are made for very high temperatures between 1000 °C (1 832°F) and 2 800 °C (5 072 °F). As a specialist in refractory metals Plansee delivers molybdenum and tungsten hot zones with an excellent form stability and lifetime. Plansee designs and produces hot zones for various types of furnaces (vacuum, protective gas atmosphere, HIP etc) and thermal processes such as sintering, brazing or annealing. Hot zones consist of countless individual parts such as heating elements, shield packs and hearth assemblies and charge carriers. You can find all of these components at Plansee. - Hot zones made from molybdenum, tungsten, tantalum, niobium and their alloys - Full metal or hybrid hot zones with graphite or ceramic fiber insulation - From very small (a few cm³) through to very large (several m³) hot zones - For temperatures of between 1000°C (1832°F) and 2800°C (5072°F) - Tailor-made design: round, rectangular, vertical, horizontal or special geometries

Metallic heaters made from ML or tungsten are made for very high temperatures between 1000 °C (1 832°F) and 2 800 °C (5 072 °F). Plansee supplies heating elements for all types of high-temperature furnace in the form of ribbon, sheets, rods, twisted wire, wire bundles and wire mesh heaters. Plansee's materials belong to the group of refractory metals. Molybdenum and tungsten are the two materials that are most commonly used in high-temperature thermal processes. Thanks to their high melting points, they do not soften even at very high temperatures. Refractory metals have a lower coefficient of thermal expansion and better thermal conductivity than steel.

Shielding components made from tungsten, molybdenum and the tungsten heavy alloy Densimet® only allow radiation to pass where it is actually needed. During the generation of X-ray radiation our materials guarantee that environmental radiation exposure is kept to an absolute minimum. Plansee produces flat shielding components using an innovative, near net shape process. The result: The foils and sheets have a particularly isotrope and homogeneous microstructure free from any characteristic orientation. Possible products and applications are: — Shielding components for X-ray tubes — Shutter blades for computer tomographs — Shielding elements for detectors — Isotope containers for brachytherapy — Shielding elements for linear accelerators — Shieldings for oil and gas drilling

Welding electrodes made of tungsten, molybdenum and their alloys are particularly suitable for welding highly conductive materials such as copper. They are used in the following processes: Spot welding, Roller welding, Projection welding, Upset welding. Welding electrodes made from our refractory metals and their alloys have a relatively high level of electrical conductivity while also exhibiting outstanding stability at high temperatures. They therefore have a considerably longer service life than conventional materials such as copper and copper alloys.

Spare parts include for example chambers, filaments, arc slits, holders and many other parts. The pare parts are made of graphite, molybdenum, tungsten and alloys.
