Ø Product Name: Tungsten Wire
Ø Model: NB3 （0.81×3）-7×8×18×32
Ø Material: Tungsten（99.95%）
Ø Grade: WAL1 Tungsten Wire
Ø Property: Specially made for vacuum metalizing, with the characteristic of high melting point, anti-corrosion, good performance and long life etc.
Ø Application: Mainly applied as heating element for vacuum metalizing in car light, mirror, plastic, ABS, PP and decorations etc.
Ø Working Process: Tungsten with high melting point, high resistance, good intensity and low evaporation pressure, suitable for making heating element. Placing film material (aluminum, chrome, indium etc.) in vacuum chamber, with high vacuum, the heating element (tungsten heater) will evaporate the film into air, that means the evaporation molecule (or atom) emitted from film material. When the diffusion mean free path of evaporation molecule gets longer than the size of chamber, with rare interfere of other air molecule, the evaporation molecule (or atom) could reach the substrate. As a result of low temperature, the evaporation molecule would condense on the substrate, turn into shiny and beautiful film.
