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

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.

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

Molybdenum-hafnium carbide (MHC) is highly temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. At higher temperatures, the producer recommends using MHC for full dies. The benefits to you for a long service life: — Optimum nondeformability and dimensional stability — Low tendency to crack in the case of edged profiles — High thermal stability — High thermal conductivity — Low thermal expansion — Good hot ductility — Very high recrystallization temperature Plansee supplies MHC components in disc form with or without drilled start hole.

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

Nozzle tips for hot runner nozzles made of titanium-zirconium-molybdenum offer particularly high thermal conductivity of 140 W/mK coupled with excellent temperature and corrosion resistance. Glass fiber-reinforced plastics are exceptionally strong during processing but also highly abrasive. An optimum combination of thermal conductivity and material hardness is required. The TZM nozzle tips of Plansee are exceptionally resistant to aggression: the SHN surface hardening process. Using SHN surface hardening, we can strengthen peripheral areas and entire TZM components through the addition of a permanent, adherent diffusion layer. As a result, our customers benefit from the use of a tough, heat-resistant material with a wear-resistant surface. Surface hardening takes place during the gas phase. Coatings that we produce using the SHN process adhere better than conventional PVD or CVD layers. They perfectly replicate the surface contour of the TZM product.

Plansee produces material for wear-resistant coatings, adhesive layers, decorative or DLC coatings. Offering compositions tailored for advanced hard coatings with optimized mechanical and tribological properties. Further topics that might be addressed are: enhancing of thermal and chemical stability, adding of functional properties like self-lubrication, self-hardening and self-healing. To adjust the coating characteristics to the dedicated application, Plansee offers its scientific expertise in alloying of targets and cathodes with elements that influence the coating properties as follows: Grain size and morphology, Hardness adaption, High temperature oxidation resistance, Friction coefficient, Thermal stability, Thermal conductivity, Electrical conductivity, Antibacterial properties, Color effects. Offered sputtering targets and arcing cathodes: Titanium-Aluminum Aluminum-Chromium Chromium Titanium-silicon Titanium Zirconium Tungsten carbide Titanium-diboride

Tungsten layers are components of the thin-film transistors used in TFT-LCD screens. They are used wherever large screen formats, particularly high image definition and optimized contrasts are needed. But tungsten is also used as a diffusion barrier and a conductive connector in the microelectronics industry. Using the world's largest hot rolling mill for refractory metals, Plansee is able to produce the largest tungsten sputtering target on earth. The benefit to you of large formats: The coating process is more stable and the deposited layers are of higher quality. Thanks to the special forming processes Plansee's tungsten sputtering targets have a density of almost 100 %. As a result, your process benefits from a particularly high level of conductivity and time savings due to the excellent sputtering speeds.

Molybdenum sputtering targets are used for the manufacture of thin-film transistors used in TFT-LCD screens. Targets from Plansee are maximum dense, highly pure and show a homegenous microstructure. Therefore higher sputtering speeds, minimized particle formation during the process and homogenous layers are guaranteed. Available molybdenum alloys: MoTa, MoNb, MoNa, MoW You can choose between our single and multi-piece planar targets. Planar targets are available for all commonly used systems as well as to specific customer needs. Rotary targets are available too.
