Electron Beam Tungsten Filaments
Product Description
Tungsten filaments have a high melting point, high resistivity, good strength, and low vapor pressure, and can be used in electron beam evaporation systems. Electron beam tungsten filaments can withstand the high temperatures generated during the vaporization process, ensuring reliable and efficient operation of the evaporation process.
Electron beam tungsten filaments are an essential component in vacuum deposition systems, which use the energy of electron bombardment to evaporate the target material. This evaporation process produces a stream of atoms or molecules, which deposits a thin film with excellent uniformity, density, and purity.
We manufacture tungsten and some OEM filaments for popular electron beam systems, including:
• JEOL
• Leybold
• Telemark
• Temescal
• Thermionic
We support customization of more specifications and shapes. Please contact us if necessary.
The packaging is usually one box (10 pieces), which is also the minimum MOQ.


Applications
Electron beam tungsten filaments are widely used in many industries and fields such as semiconductor manufacturing, optics, aerospace and automotive. It is used to deposit thin films of metals, oxides and other materials onto substrates for applications such as integrated circuits, optical coatings, solar cells and decorative topcoats.
