Tungsten electrodes - Import export

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.

EDM Electrodes made of the tungsten alloy SPARKAL are available as tubes, rods, square rods and plates in different dimensions in the Plansee Online Shop. Order fast and easily from the producer's online shop: www.plansee.com/shop.

The following nozzles and electrodes made of tungsten-copper are available from stock: Nozzles: — PN-F4-6 — PN-F1-6 — PN-G-W / PN-GH-W Electrodes: — PE-F4 — PE-F1-45 / PE-F1-90 — PE-3M63 / PE-7M63 / PE-9M63 Thanks to its high melting point, tungsten ensures that even the high temperatures that occur at the particularly exposed tip cause no damage to the spray nozzle. The high level of thermal conductivity provided by tungsten and copper ensure optimum heat dissipation. As a result, our nozzles and electrodes offer excellent resistance to arc erosion. This guarantees a long service life. — outstanding arc erosion resistance — high temperature resistance — optimum thermal conductivity

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.
