Application: Vacuum coating
Chemical Composition: Tungsten 3N5
Tungsten filaments, made of tungsten wires, have high melting point ans good corrosion resistance.
They are mainly used for vacuum metallizing, such as heating elements for chrome scope, mirrors, plastics and decoration articles.
Tungsten Filaments can be stranded into single or multi wires according to the samples or drawings of customers. Pure wire and doped wire are both available. Diameter of tungsten wire: 0.2-1.2mm.
