Application of tungsten Filament wire
Electric light source with stranded tungsten wire can be used in a variety of bulbs, its melting point is high, electrical conductivity is also better, mainly used in incandescent lamps, halogen lamps, fluorescent lamps and so on
Vacuum coating: Tungsten skein can be used in vacuum coating equipment as a heater for picture tubes.
Electronics and semiconductor industry: In the electronics and semiconductor manufacturing process, tungsten twisted wire can be used as a heater for electronic tubes and a reinforcement of composite materials to improve the performance and stability of equipment
Other industrial applications: In addition, tungsten Filament wire is also widely used in metal evaporation, mirror industry, gas discharge lamp electrodes and glass metal sealing components and other fields.
What is the difference between tungsten wire and tungsten Filament wire ?
Materials and manufacturing processes
tungsten wire : Tungsten wire is made of tungsten bar after forging and drawing. Mainly used in lamp manufacturing, such as incandescent lamp and tungsten halogen lamp luminous body .
tungsten twisted : Tungsten twisted wire is usually made of tungsten alloy core wire and outer coating material. The outer coating material is usually a special ceramic material used to improve its high temperature resistance and oxidation resistance.
Manufacturing process:
Tungsten wire: After forging, repeated drawing to make a finer wire
tungsten Filament wire : by a single or multiple strands of tungsten wire winding, tungsten wire will be twice inspected during the production process to ensure that the wire diameter uniform, no internal cracks and other defects
Can tungsten Filament wire work stably at high temperature?
This stability is mainly due to the special material composition and structure of tungsten twisted wire. The stability of tungsten twisted wire is derived from its structure, it is produced by tungsten alloy wire, with high strength, high density, and most importantly, it is resistant to high temperature. Tungsten Filament wire can work at high temperature
rties stable, not easy to deformation, cracking or oxidation. Therefore, tungsten skein can maintain its stable working performance under high temperature environment, showing good heat resistance and stability.

Tungsten Filament wire production method
Raw material preparation: The production of tungsten twisted wire selects high quality tungsten wire as raw material. For example, HW41HW42.
Drawing treatment: The tungsten wire is stretched by a wire drawing machine to the desired diameter. In this step, the speed and temperature of the drawing need to be strictly controlled to ensure that the quality and performance of the tungsten wire are not damaged.
Stranding process: The stretched tungsten wire will be twisted.The drawing machine into fine wire tungsten wire in accordance with customer requirements wrapped together, can be made into tungsten skein. When winding, it is necessary to pay attention to whether it is uniform to ensure that the performance of the tungsten skein remains unchanged.
Heat treatment: After the stranding is completed, it needs to be heat treated in order to eliminate its stress to improve the stability of the material.
Quality inspection: We have a professional quality inspection department to test the quality of tungsten Filament wire . Guarantee to meet customer requirements
Incandescent lamp used for a long time black is what reason?
Incandescent inside the light is tungsten wire, because tungsten is a black solid, so tungsten in the inner wall of the lamp keeps accumulating, the lamp is black. Tungsten wire can maintain stability at higher temperatures and will not melt away, but directly into a gas, such as closed after the temperature is reduced, tungsten gas again becomes a solid stick to the bulb wall.
