Tungsten Filament Evaporation Coils for Vacuum Metallization
Tungsten Evaporation Filaments
Tungsten evaporation filaments are mainly used in vacuum metallization processes. Vacuum metallization is a process that forms a metal film on a substrate, coating a metal (such as aluminum) onto a non-metallic substrate by thermal evaporation.
Tungsten has the characteristics of high melting point, high resistivity, good strength, and low vapor pressure, making it an ideal material for making evaporation sources.
Tungsten evaporation coils are made of single or multiple strands of tungsten wire and can be bent into various shapes according to your installation or evaporation needs. We provide you with a variety of tungsten strand solutions, welcome to contact us for preferential quotes.
