CTIA’s Tungsten Heater Specifications
Tungsten heater specifications are mainly classified according to parameters such as tungsten wire diameter, strand number, shape and detailed dimensions. As of April 2026, based on CTIA GROUP’s more than 30 years of design and manufacturing experience, combined with various customer requirements and public technical references, the common tungsten heater specifications are summarized below.
The specifications of tungsten heater are essentially comprehensive engineering requirements involving structure, material, electrothermal parameters and application matching, rather than simple dimensional definitions. Based on CTIA GROUP’s manufacturing experience and commonly used industry parameters, the following classification system is summarized.
1.Classification of Tungsten Heater by Tungsten Wire Structural Parameters
Tungsten heater specifications are determined by structural parameters such as tungsten wire diameter, strand number, twisting method and pitch.The table below shows the structural parameter system of tungsten heater wire materials.
2.Classification of Tungsten Heater by Structural Shape
Tungsten heaters can be classified according to geometric structures, such as straight type, helical type, U-shape type, funnel type, grid type, tungsten basket and tungsten boat.The table below shows tungsten heater structural types and related applications.
3.Classification of Tungsten Heater by Dimension Expression Method
The following format is generally used to express tungsten heater specifications:
Structure (wire diameter × strand number) – dimensional parameters (mm).
The table below shows typical tungsten heater specification examples.
4.Tungsten Heater Material and Performance Specifications
Specifications are defined based on material performance parameters including purity, melting point, electrical resistivity, and operating temperature.The table below shows tungsten heater material and performance parameters.
5.Classification of Tungsten Heater by Application Power and Electrical Parameters
Electrical parameters rather than dimensions are the key factors affecting selection.The table below shows the key electrothermal design parameters of tungsten heater classification.
6.Classification of Tungsten Heater by Material System
Tungsten heaters can also be classified into pure tungsten, doped tungsten and tungsten alloy systems.The table below shows the characteristics of different tungsten heater materials.
7.Essence of Tungsten Heater Specification Design
Tungsten heater are not standardized products, but engineering products designed according to customer requirements and operating conditions. The core design concept involves four matching relationships: (1) electrical parameter matching (voltage, current and resistance), (2) thermal field matching (uniformity and radiation area), (3) structural matching (equipment space and installation method), and (4) atmosphere matching (vacuum or protective gas).
This is why the industry contains a large number of customized models instead of unified standard models. Tungsten heater specifications are essentially engineering parameter combinations designed around temperature, current, structure and service life. In practical applications, customers need to provide not only dimensions, but also operating temperature, heating target, power supply conditions, installation space and expected service life. Only when these requirements are fully matched can the design and manufacturing process achieve practical engineering significance.
