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

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.

Tungsten layers are components of the thin-film transistors used in TFT-LCD screens. They are used wherever large screen formats, particularly high image definition and optimized contrasts are needed. But tungsten is also used as a diffusion barrier and a conductive connector in the microelectronics industry. Using the world's largest hot rolling mill for refractory metals, Plansee is able to produce the largest tungsten sputtering target on earth. The benefit to you of large formats: The coating process is more stable and the deposited layers are of higher quality. Thanks to the special forming processes Plansee's tungsten sputtering targets have a density of almost 100 %. As a result, your process benefits from a particularly high level of conductivity and time savings due to the excellent sputtering speeds.
