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.

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.
