What's Spiral Tungsten Wire?
What Is Spiral Tungsten Wire?
Spiral tungsten wire, alternatively known as spiral tungsten heater, is a high-temperature resistance heating element manufactured from high-purity tungsten wire with a purity of not less than 99.95% through precision winding processes into a helical structure. It is primarily utilized for high-temperature heating and evaporation processes within vacuum environments or inert gas systems.
What Are Advantages of CTIA's Spiral Tungsten Wire?
1. High-temperature stability: With a melting point of approximately 3,422°C, tungsten maintains exceptional creep resistance and structural integrity at temperatures exceeding 2,000°C.
2. Low contamination: Low vapor pressure effectively minimize volatilization contamination at high temperatures, preserving vacuum environment cleanliness.
3. High-temperature environment compatibility: Operate reliably within vacuum atmospheres or inert gases such as argon and nitrogen, covering temperature ranges from 1,800°C to 2,800°C.
4. High power density: Helical design increases effective heating wire length, which elevates heating capabilities per unit volume.
5. Rapid thermal response: Optimized thermal field distribution ensures accelerated heating rates and low thermal inertia.

What Are Applications of Spiral Tungsten Wire?
Spiral tungsten wire is widely utilized in vacuum evaporation coating, electron beam evaporation preheating, semiconductor thermal processing, optical thin-film deposition, and high-temperature laboratory vacuum furnaces, making it ideal for thermal systems demanding high power densities and quick response times.
How To Select Spiral Tungsten Wire?
Tungsten wire diameters for spiral tungsten heaters typically range from 0.2 mm to 1.2 mm, with different power ratings achieved by adjusting spiral diameters, pitches, and number of turns. Tight spiral configurations are suited for concentrated high-power heating scenarios, whereas loose structures are preferred for temperature gradient control or uniform heating requirements. Variations in these structural parameters directly govern heating speed, thermal inertia, and thermal field uniformity.
Leveraging over three decades of manufacturing expertise in tungsten heater, CTIA GROUP delivers optimized, custom-engineered designs tailored to specific equipment structures and thermal fields. To ensure maximum operational consistency in high-temperature vacuum systems, every spiral tungsten wire solution integrates custom-engineered spiral diameters, pitches, heating lengths, and lead-out designs with advanced forming and proprietary surface treatments.
