Tungsten coiled wire
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.
Specification of Tungsten Coiled Wires:
Density: 19.3g/cm3
Type: WAL-1, WAL-2, WAL-3 etc.
Content: W≥ 99.95%
Character and usage
It has good character in high temperature and endurance, mainly used as filament wire in halogen filament, high temperature color filament, twist filament, white filament and fluorescence filament.
Advantages of Coiled Tungsten Wires:
High temperature performance
High recrystallization temperature
Good machining performance
Good resistance to high tmperature sag performance
Good acid and alkali resistance to room temperature
