Tungsten is a metal known for its high melting point and excellent electrical conductivity.
The wire is typically coiled or stranded to increase the surface area and enhance heat transfer.
Tungsten stranded heaters are commonly used in various industrial applications, such as semiconductor manufacturing, vacuum furnaces, and high-temperature environments.
Tankii Tungsten heaters are known for their durability, high temperature resistance, and precise heating capabilities.

Polishing and white surface products are available, special sizes can be manufactured based on customers' requirements.
 

 

Operating principle of tungsten heating elements:
tungsten has high melting point, high resistivity, good strength and low steam pressure, which is suitable for heating.
The film material is placed in a heater in the vacuum chamber.
Under high vacuum conditions, it is heated by a heater (tungsten wire heater) to evaporate.
When the Mean free path of the vapor molecule is greater than the linear size of the vacuum chamber, the atoms and molecules of the vapor escape from the surface of the evaporation source, are less impacted and hindered by other molecules or atoms, and can directly reach the surface of the substrate to be plated. Due to the low temperature of the substrate, they condense on it to form a film.
 
Performance characteristics: Selected WAL1 tungsten wire as raw material, the heating element produced by professional equipment has characteristics such as high melting point, good corrosion resistance, and long evaporation life.
