Tungsten Heater Classification
Based on more than 30 years of tungsten heater manufacturing and customer support experience, CTIA GROUP provides a systematic tungsten heater classification covering structural shape, tungsten wire strand count, forming method, material type and application field. The classification of tungsten heater may help customers select suitable products for different vacuum heating and high-temperature process requirements.
1.Classification by Structural Shape
Different structures directly influence current distribution, thermal field uniformity, material holding capacity and evaporation efficiency. Proper selection should be based on evaporation method, loading mode and temperature control requirements.The following table shows the structural types of CTIA’s tungsten heaters.
2.Classification by Tungsten Wire Strand Count
Wire strand count directly affects mechanical strength, sag resistance, thermal deformation resistance and service life.The following table shows the tungsten wire strand count of CTIA’s tungsten heaters.
3.Classification by Forming Method
Different forming methods affect dimensional accuracy, structural consistency, surface quality and long-term operating reliability.
Straight drawn tungsten heater: High dimensional accuracy, good consistency and stable electrical performance. Suitable for standardized production and batch applications.
Twisted formed tungsten heater: Strong flexibility and improved fracture resistance. Suitable for vibration conditions or thermal cycling environments.
Coiled formed tungsten heater: Flexible structure with adjustable resistance and heat distribution. Suitable for complex structures and customized heating systems.
4.Classification by Material Type
Material type directly affects high-temperature mechanical properties, creep resistance, sag resistance and service stability.
Pure tungsten heater: High purity and stable electrical conductivity. Suitable for conventional vacuum evaporation and laboratory high-temperature heating.
Doped tungsten heater: Better sag resistance and creep resistance, with stronger structural stability at elevated temperature. Suitable for long-term semiconductor equipment operation and continuous industrial furnace production.
5.Classification by Application
Different applications determine structural form, heating mode, power distribution and thermal field requirements. The following table shows the applications of CTIA’s tungsten heaters.
