    Tungsten Evaporation Filaments

    A tungsten evaporation filament is a crucial component used in physical vapor deposition (PVD) processes, specifically in thermal evaporation. PVD is a technique employed for depositing thin films on various surfaces, and tungsten evaporation filaments play a key role in this process.

    Tungsten filaments are widely used for thin film deposition of various metals and alloys. They are used to vaporize metal wire or foil that can be inserted into a coil of filament or a thin wire can be wound around the coil. The evaporation process involves melting metal to wet the filament coil and then increasing power to evaporate the molten metal. It can be used for thin film deposition of aluminum, as well as gold, silver, nickel, aluminum, titanium, and other metals.

    Tungsten evaporating coils are made of single-strand or multi-strand tungsten wire, which can be bent into various shapes according to installation or evaporation needs. We provide customers with various tungsten-stranded wire solutions, welcome to consult.
