CTIA's Tungsten Heater in Laboratory Vacuum Heating
CTIA’s tungsten heater is a tungsten heating element used in laboratory vacuum heating applications, manufactured from high-purity tungsten wire through precision drawing, stranding, winding, forming, and surface treatment processes. Tungsten heater generates a stable and uniform thermal field under high vacuum or protective atmosphere conditions and is widely used in university laboratories, research institutes, and industrial R&D centers for material heat treatment applications such as vacuum sintering and vacuum annealing.
Tungsten heater is designed for laboratory vacuum heating systems requiring limited space, high vacuum conditions, and precise temperature control. It has a melting point of about 3410℃ and maintains structural stability at high temperatures without deformation. The tungsten heating element also exhibits low vapor pressure, reducing evaporation and helping maintain chamber cleanliness. Stable electrical properties enable efficient heat generation and uniform thermal field distribution through radiation. A low thermal expansion coefficient further reduces deformation during repeated heating and cooling cycles, improving experimental stability and repeatability.
Specifications of CTIA’s tungsten heater in laboratory vacuum heating applications:
（1）Material: Pure tungsten wire with purity ≥99.95%.
（2）Wire diameter: 0.2–1.2mm, customizable.
（3）Stranding structure: Single strand or multi-strand twisted structures.
（4）Geometry: Straight, spiral, U-frame, coil, and customized shapes.
Tungsten heater is often applied to vacuum heat treatment furnaces, small vacuum sintering furnaces, and high-temperature material testing equipment.
CTIA GROUP specializes in tungsten heater engineering and provides system-level optimization solutions based on laboratory equipment dimensions, power requirements, vacuum level, and thermal field distribution needs. Design considerations include tungsten wire diameter, doping type and content, structural configuration, effective heating length, and lead wire structure. Surface treatments such as electrolytic polishing and alkali cleaning are available to enhance surface quality and operational stability. CTIA offers end-to-end customization from material selection and structural design to precision manufacturing.
