What is Tungsten Twisted Wire Heater?
Tungsten twisted wire heater is a resistive heating element further processed from stranded tungsten wire. Compared with tungsten wire heaters, tungsten twisted wire heater offers better creep resistance and structural stability in high-temperature environments. During long-term operation or repeated heating and cooling cycles, it is less prone to deformation or fracture, making it more suitable for continuous operation conditions. Its working temperature can typically reach above 2000°C, depending on the vacuum or inert gas environment and structural design.
Based on over 30 years of experience in tungsten heater manufacturing, CTIA GROUP first mechanically twists multiple tungsten wires into a stable stranded structure and then forms them into various geometries according to application requirements, including U-shaped, straight, spiral, wave, funnel and door-type configurations. These designs improve mechanical strength while ensuring more uniform current distribution, resulting in stable and consistent heating performance.
Tungsten twisted wire heater is widely used as a heating element in Physical Vapor Deposition (PVD) evaporation coating processes, particularly for the evaporation of aluminum, silver and gold. It is also applied in optical coating, decorative coating, capacitor metallization and vacuum electronic heating components.
Typical specifications include wire diameters ranging from 0.2 to 1.8 mm, with 2 to 4 strands commonly used. With over 30 years of experience in tungsten heater manufacturing, CTIA GROUP provides system-level customization based on equipment configuration and thermal field requirements, including wire diameter selection, doping type and content, structural design, effective heating length and lead configuration. Supported by appropriate surface treatment processes, CTIA GROUP delivers full-process customization from material selection to precision manufacturing.
