99.95% Customized Pure Tungsten Wire Tungsten Coiled Wires For Thermal Coating
Tungsten coiled wire is also called tungsten heater or tungsten stranded wires. It is a metal composed of single-strand or milti-strand doped tungsten wires of different shapes. Because of its good corrosion resistance,high-temperature performance,stability and long using life, it is widely applied in mirror industry, kinescope industry, vacuum plating, metal vaporization and other fileds. We can produce tungsten coiled wires of different specifications and shapes.
