Advantages of tungsten heating elements

Tungsten heating elements have many advantages, among which the following are several aspects:

High melting point: Tungsten has a melting point of up to 3410 ℃, which can maintain good stability at high temperatures without melting or decomposing, thus ensuring the service life of heating elements.

High density: Tungsten has a density of 19.35g/cm3, which is heavier than other metal materials and can better withstand high temperatures and pressures.

High thermal conductivity: Tungsten has high thermal conductivity and can quickly transfer heat to the surface of heating elements, thereby improving heating efficiency.

Good high-temperature strength: Tungsten has good strength and hardness at high temperatures and can withstand high temperatures and pressures, ensuring that heating elements do not deform or rupture.

Good corrosion resistance: Tungsten is not easily oxidized or corroded at high temperatures and can resist various chemical corrosion, thus ensuring the reliability and stability of heating elements.

Application Fields of Tungsten Heating Elements

Due to the advantages of tungsten heating elements, they have been widely used in many fields. The following is an introduction to several main application areas:

Vacuum furnace: In a vacuum furnace, tungsten heating elements can withstand high temperatures and vacuum environments, thereby ensuring the stability and heating efficiency of the furnace. For example, in a vacuum coating machine, tungsten heating elements can heat the substrate to the required temperature for coating.

Atmosphere furnace: In an atmosphere furnace, tungsten heating elements can withstand high temperatures and chemical corrosion, thereby ensuring the stability and heating efficiency of the furnace. For example, in a carbon tube furnace, tungsten heating elements can heat the carbon tube to the desired temperature for synthesis.

Electric arc furnace: In an electric arc furnace, tungsten heating elements can withstand high temperatures and arc impacts, thereby ensuring the stability and heating efficiency of the furnace. For example, in steelmaking electric arc furnaces, tungsten heating elements can improve molten steel's purity and quality.

Other high-temperature equipment: In addition to the above application fields, tungsten heating elements can be applied to other high-temperature equipment, such as ceramic kilns, glass kilns, etc.

mainly used as heating elements in surface vacuum coating process such as aluminum spraying, chrome-plated, mirror making, ceramic coating and plastics coating, etc.
