Where Our Tungsten Wire Excels
Tungsten stranded wire is designed for vacuum coating and evaporation source applications in high-vacuum thermal deposition systems. It is commonly used in tungsten wire baskets, evaporation filaments, and resistance-heated source assemblies for thin-film coating processes.
Typical Applications
- Optical coating for lenses, filters, and glass substrates.
- Vacuum metallizing for decorative and functional thin films.
- Semiconductor and electronic thin-film deposition.
- Laboratory and pilot-scale thermal evaporation equipment.
Why It Works
Tungsten offers a high melting point and stable performance under intense heat, making it suitable for resistance heating in vacuum environments.
Its structure helps support efficient and controlled evaporation of coating materials, improving source stability and service life.
Why Choose Yolo As Your Trust Supplier?
Strong Sourcing Advantages

100% Eddy Current Detection
We protect your production quality by testing every rod—including wire ends as thin as 0.39 mm. All sub-Grade C materials are strictly removed, preventing cracks from becoming a problem in your downstream operations and drastically reducing costly wire breakage.
100% Eddy Current Testing on wires down to even 0.39mm.
Yolo’s advanced drawing equipment
Many other manufacture’s traditional equipment
German Rolling Mill Technology
Our advanced process deeply refines the rod core, creating a more uniform internal structure rather than just surface treatment. This translates into better consistency, superior drawability, and stronger performance for your most demanding industrial applications.

Frequently Asked Questions
What is stranded tungsten wire used for?
It is primarily used as heating elements (evaporator coils) in vacuum thermal evaporation. The stranded structure creates capillary forces to securely hold molten evaporant like aluminum, preventing dripping.
Pure vs. Doped (WAL) tungsten wire?
Pure tungsten becomes brittle after heating cycles. Potassium-doped (WAL) tungsten maintains a stable, interlocking microstructure at extreme temperatures, providing “non-sag” properties and heavily extending coil life.
Can I customize the twist pitch and strands?
Yes. We customize wire from 1-ply to 10+ strands and adjust the twist pitch to match the exact electrical resistance required by your specific vacuum chamber.
Do you manufacture ready-to-use heater coils?
Yes. Besides spooled wire, we manufacture pre-formed tungsten evaporator coils bent exactly to your technical drawings.
