Tungsten and molybdenum - Import export

Plansee supplies sintering and annealing boats made of molybdenum, tantalum, niobium, tungsten and various alloys such as ML or TZM. They are dimensionally stable, corrosion resistant against many chemicals and have a very good creep resistance. Whether is is continuous or batch furnaces - Plansee has the right solution at hand. For best quality surfaces we supply sintering and annealing boats with coatings made of aluminum and zirconium. Plansee produces its boats according to the customer's drawing in different sizes and shapes.

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.

Molybdenum and tungsten crucibles from Plansee are the perfect vessels for melting and solidifying the single crystal. The formed crucibles have particularly thin walls combined with excellent creep resistance. The outstanding purity of the crucibles prevents any contamination of the single crystal. Even the most aggressive sapphire melts cannot do any harm. Plansee produces large numbers of formed molybdenum and tungsten crucibles and supplies them in all commonly used dimensions. They are successfully used by all the major manufacturers and numerous end customers worldwide.

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

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. They are extremely durable and long lasting and therefore save money and maintenance time. 100 or more Plansee components are at work in every beam path. They ensure that the ions are generated efficiently and guided precisely and free from impurities along the beam path to the wafer. For customers in the semiconductor industry, Plansee spare parts are increasingly becoming more than just spares. Taking the equipment manufacturer's original spare parts as starting point, Plansee optimizes the geometries and material compositions. The benefits to you: — Simplified component installation and removal — Longer service lives — Lower cleaning costs — Reduced maintenance work — Reduced downtimes

Evaporation boats made of tungsten, molybdenum and tantalum are available in many different widths, lenghts, material thicknesses and volumes directly in the Plansee Online Shop: www.plansee.com/shop. Special dimensions are available on request.

Evaporation coils are available in many different lenghts, diameters, coil lenghts and coil pitches. These resistance heaters with their very high melting points will bring practically any metal to the boil. At the same time, their high corrosion resistance and outstanding material purity prevent any contamination of the substrate. The range includes evaporation coils made of the following materials: — Grain stabilized tungsten (WVM) for the evaporation of aluminum — Tantalum — Molybdenum — Molybdenum-lanthenum (ML) for particularly long service lives

For the high-resolution devices used in general X-ray applications, mammography, angiography and computed tomography, Plansee develops and manufactures extremely robust X-ray anodes and components for X-ray tubes. The product range includes anodes made from molybdenum alloys such as TZM and MHC with focal tracks consisting of various tungsten-rhenium alloys. Plansee manufactures molybdenum-vanadium and molybdenum-niobium targets that are specially designed for use in mammography applications and which can be optionally equipped with precious metal focal tracks. The product range also comprises material combinations including copper and precious metals and brazed graphite elements on the metallic disc. As braze materials V/Ta/Zr composites, titanium, zirconium and other materials are used. Plansee supplies anodes as ready-to-use assemblies including the rotor, heat shield and shaft.
