Tungsten copper - Import export

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

Depending on the application field you can choose from different switching contacts: — tungsten-copper (WCu) contacts for arcing contacts in SF6 circuit breakers — copper-chromium (CuCr) for vacuum interrupters — tungsten carbide-silver (WCAg) for vacuum contactors With their high wear resistance and optimum arc erosion properties, arcing contacts from Plansee can reach a service life of over 40 years. The contacts alone are not enough - Plansee assembles and connects all the necessary individual parts of the moveable and fixed switch contact and supplies you with the complete contact system ready for installation.
