Heating furnaces - Import export

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.
