Introduction
The tungsten-stranded wire is a kind of thin wire made of tungsten,
which is not easy to melt at high temperatures, so it is widely
used in various occasions requiring high-temperature environments.
Tungsten skein is divided into two types: single-crystal tungsten
skein and polycrystalline tungsten skein. Among them, the single
crystal tungsten twisted wire is suitable for applications
requiring high sharpness, such as electron sources in electron
microscopy. The polycrystalline tungsten twisted wire is suitable
for high-power electrical occasions, such as electric heaters,
lamps, and so on.

Application
1. Electric heating device
Tungsten twisted wire is a common electric heating device material,
such as electric heating wire, oven heating tube, electric furnace
heating tube, etc. All use tungsten twisted wire as a heating
element. Tungsten twisted wire is characterized by high
temperature, high strength, corrosion resistance, and other
properties, and can run stably in extreme environments for a long
time, so it is widely used in the field of high-temperature
heating.
2. Lamps
Tungsten skein is also one of the main components of the light
bulb, the invention and wide application of the light bulb and the
discovery of tungsten skein have an inseparable relationship. In
the light bulb, the main role of the tungsten skein is to make the
light bulb shine through heating. The high temperature, high
strength, and corrosion resistance of the tungsten skein wire make
the lamp glow stably for a long time.
3. Vacuum device
In vacuum technology, tungsten twisted wire is a commonly used
material. Among them, the electron tube is especially
representative. Because of its small resistance, high evaporation
temperature, and long service life, tungsten twisted wire is widely
used in electronic tubes.
4. Other
Tungsten skein is also widely used in other fields, such as rocket
engine nozzle, fiber processing, superalloy, and so on. Because
tungsten skein has the characteristics of high temperature, high
strength, corrosion resistance, etc., it has a wide range of
applications in the fields requiring high temperature, high
strength, corrosion resistance, and so on.
Advantages
1. Good high-temperature resistance
Tungsten skein has a very high melting point, which can reach 3422
degrees, so it is very suitable for use in high-temperature
environments.
2. High intensity
The material of tungsten twisted wire has a very high quality, so
the strength is very high, and it can be used in a high-intensity
working environment.
3. Good corrosion resistance
Tungsten twisted wire has good corrosion resistance and can work in
various acid and alkali environments.
4. Long life
Tungsten twisted wire has a very long service life and can operate
stably in extreme environments for a long time.
