CTIA's Tungsten Heater in Industrial Furnace
CTIA’s tungsten heater is a tungsten resistive heating element used in industrial furnace systems, fabricated from tungsten wire with purity higher than 99.95% through precision stranding, winding, pressing forming, and surface treatment processes. Tungsten heater provides a stable heat source in high-temperature industrial environments and is widely used in vacuum heat treatment furnaces, powder metallurgy sintering furnaces, brazing furnaces, and high-temperature material processing equipment.
Why is tungsten heater used in industrial furnaces? Tungsten heater delivers stable performance under harsh industrial thermal conditions to meet demanding requirements of high-temperature industrial processes. CTIA’s tungsten heater has the following characteristics:
(1) Tungsten heater has a melting point of about 3410℃ and maintains structural stability under extreme temperature conditions.
(2) Tungsten heater exhibits low vapor pressure in vacuum or protective atmospheres, reducing material loss and minimizing contamination of processed components.
(3) Tungsten heater maintains stable electrical resistance and supports uniform heat generation, forming a consistent thermal field inside the furnace chamber via radiation.
(4) Tungsten heater shows low thermal expansion, maintaining structural integrity during repeated heating and cooling cycles and ensuring long-term operational stability.
CTIA provides diversified specifications of tungsten heater for industrial furnace based on furnace structure and thermal field distribution requirements, including the following parameters:
(1) Material: Pure tungsten wire or doped tungsten wire are available.
(2) Wire diameter: 0.2–1.2mm.
(3) Stranding structure: Single strand, 2-strand, 3-strand, 4-strand, and 6-strand structures.
(4) Geometry: Straight, U-frame, spiral, wave, and coil, etc.
Tungsten heater serves as an important heating element in vacuum industrial furnaces, powder metallurgy furnaces, high-temperature sintering furnaces, and heat treatment equipment, ensuring stable temperature control and uniform thermal field distribution in industrial processes.
