What is Tungsten Twisted Wire?
Tungsten twisted wire is a structural material formed by twisting two or more high-purity tungsten wires together. It is also known as stranded tungsten wire and is widely used in high-temperature heating applications.
The twisted structure provides higher mechanical strength and improved stability under thermal stress compared with single tungsten wire. By distributing mechanical load across multiple strands, tungsten twisted wire reduces deformation and extends service life in high-temperature environments.
It also improves heat distribution by forming a more uniform thermal conduction path, resulting in stable and consistent heating performance in vacuum evaporation and coating processes.
Tungsten twisted wire is one of the most commonly used heating materials in Physical Vapor Deposition (PVD) processes for metal evaporation, optical coating, and electronic device manufacturing applications.
CTIA GROUP uses high-purity tungsten wire (≥99.95%) and applies controlled twisting processes to ensure structural uniformity and consistent strand alignment, delivering reliable performance in high-temperature conditions.
Depending on application requirements, tungsten twisted wire can be used directly as a heating element or fabricated into different tungsten heater structures, including evaporation coils, tungsten baskets, filaments, and customized evaporation sources. Typical wire diameters range from 0.2 to 0.8 mm, with 2–4 strands commonly used.
With over 30 years of experience in tungsten heaters, CTIA GROUP provides application-based customization, including structural design, wire specification, and process optimization for vacuum and thermal systems.
