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.

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

Tungsten and tungsten alloy electrodes are used to produce the arc in high-intensity discharge lamps. Tungsten electrodes from Plansee excel due to their outstanding physical and mechanical properties: a high melting point, low vapor pressure, low thermal expansion, good thermal conductivity and a low electron work function. Plansee supplies anodes, cathodes and support rods. With special alloy additives, Plansee improves the high-temperature dimensional stability, electron work function, formability, machinability and thermal conductivity of the material. For cathodes, aluminium-potassium silicate (AKS) or lanthanum oxide-doped tungsten is available. A new addition to the range: WLZ, a tungsten material doped with lanthanum and zirconium oxide. WLZ is the non-radioactive alternative to thorium-doped materials.

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.

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

Plansee collimators are made of tungsten heavy metal alloys (Densimet® alloys). Due to the high density of the material, collimators perfectly shield from x-rays and gamma rays and therefore protect the healthy tissue during radiotherapy. Densimet® tungsten alloys are distinguished by their particularly high density. Combined with their ability to absorb radiation as well as their outstanding mechanical properties and machinability. Particular material properties: — high density of 17.0 to 18.8g/cm³ — better machinability compared to pure tungsten — high Young’s modulus and very good mechanical properties — high absorption capacity for X-rays and gamma rays — harmless to the health and environment

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.

Rods made of molybdenum and the molybdenum alloy TZM are available in the diameter range 2mm to 165mm in different lengths in the Plansee Online Shop. Order fast and easily from the producer's online shop: www.plansee.com/shop. Special dimensions are available on request.
