Application
Electric Light Source Industry
A small amount of potassium, silicon and aluminum oxides are added during the smelting process.
This kind of tungsten wire is called doped tungsten wire (Doped Tungsten Wire), also known as 218 tungsten wire or non-sag tungsten wire (Non-sag Tungsten Wire).
Used in incandescent lamps, tungsten halogen lamps and other electric light sources.
Semiconductor and Photovoltaic Industry
Ultra-fine tungsten wire for photovoltaics is a new material and is mainly used as consumables for cutting semiconductor and silicon materials for solar photovoltaics.
Tungsten alloy wire is a key core technology for precision cutting and processing of hard and brittle functional materials due to its high strength, good fatigue resistance, good electrical conductivity, and high potential for thinning.
Compared with traditional carbon steel bus bars, tungsten wire has the advantages of thinner wire diameter, less cutting material loss, and higher production efficiency. It has shown a trend of replacing carbon steel wire and is gradually increasing market penetration.
Home Appliance Industry
The principle of electrostatic precipitating is to use high-voltage tungsten to cause the tungsten wire to release strong ionization energy, connecting the particles in the air in series and adsorbing them to the dust collection device, thereby purifying the air.
The advantages of tungsten wire dust removal technology include ionization, long-term consumption and low energy consumption. Tungsten wire has high temperature resistance, corrosion resistance and other properties, and can work stably for a long time in extreme environments, improving the purification efficiency and service life of the equipment.
Our special tungsten wire for electrostatic precipitator can be used as electrodes in oil fume purifiers, electrostatic precipitator equipment, and air purifiers.
Window Glass Heating Industry
The principle of heating car window glass is mainly to embed resistance wire or conductive coating inside the glass. When electricity is energized, the resistance wire or conductive coating will generate heat, thereby increasing the surface temperature of the glass to achieve the effect of defogging and defrosting. . 
Tungsten wire is an ideal choice for car window heating systems because of its high melting point, high hardness, and good electrical and thermal conductivity.
Vacuum Coating Industry
The special tungsten twisted wire for the vacuum coating industry is made of tungsten wire and is produced by winding single or multiple strands of tungsten wire.
The principle of vacuum coating is to place the film material in the heater in the vacuum chamber. Under high vacuum conditions, it is heated by the heater (tungsten wire heater) to evaporate it. When the mean free path of the vapor molecules is greater than the linear size of the vacuum chamber Later, after the atoms and molecules of the vapor escape from the surface of the evaporation source, they are rarely impacted and hindered by other molecules or atoms, and can directly reach the surface of the substrate to be plated. Since the substrate temperature is low, they condense on it and form Film formation.
