W shape tungsten wire filaments for vacuum coating metallizing

Product Overview

Description

W shape tungsten wire filaments for vacuum coating

Tungsten has a high melting point, high resistivity, good strength low vapor pressure, it is suitable for making heating elements. Placking film material (aluminum, chrome, indium etc) in a vacuum metalizing machine, with high vacuum, the heating elements will evaporate the film turn into shiny and beautiful film.
