In What Fields Is Tungsten Wire Widely Used?

Due to its excellent physical and chemical properties, tungsten wire is widely used in many fields, including but not limited to:

Electronic technology: Tungsten wire is used as an electron emitter in electronic devices, such as the anode of electron tubes, X-ray tubes and television picture tubes. They are also used in electron beam etching and electron beam welding in semiconductor manufacturing.

Lighting: Tungsten filament was once widely used in incandescent light bulbs, where an electric current is passed through the filament to heat it and cause it to glow. Although new technologies such as LED are now gradually replacing traditional incandescent lamps, tungsten lamps are still used in some special applications.

Vacuum Equipment: Due to its high melting point and resistance to oxidation, tungsten wire is used in vacuum equipment and vacuum tubes as heating elements and electron emitters.

High Temperature Heaters: Tungsten wire is used to make high temperature resistance heaters for a variety of applications including industrial heat treatment, smelting and drying.

Photovoltaic Industry: In the photovoltaic industry, tungsten wire is used to cut silicon wafers to make solar cells.

Aerospace: Tungsten wire is used in the aerospace industry to manufacture components and electronic equipment in high-temperature environments.

Medical field: Tungsten wire is used in medical equipment to make high-frequency electrosurgical blades for surgery and tissue cutting.

Semiconductor Manufacturing: Tungsten wire is used in several steps in semiconductor manufacturing, including CVD (Chemical Vapor Deposition) and PECVD (Plasma Enhanced Chemical Vapor Deposition) processes.

Chemical Analysis: The tungsten filament is the part of the mass spectrometer used to generate electrons for sample analysis.
