CTIA's Tungsten Heater in Heat Treatment
CTIA’s tungsten heater is a specialized tungsten heating element for vacuum heat treatment furnaces or protective atmosphere furnaces. It provides a high temperature controlled thermal field for processes such as annealing, quenching, tempering, and stress relief of metallic materials. Fabricated from tungsten wire with a purity of ≥ 99.95% or doped tungsten wire, the tungsten heater undergoes drawing, stranding, pressing, and advanced surface treatments including electrolytic polishing and alkaline cleaning. And it is widely adopted across sectors such as vacuum annealing, quenching, stress relief treatment, and high-end metal thermal processing.
The precision of heat treatment directly dictates the mechanical properties and microstructure of the workpiece. Tungsten heater produced by CTIA GROUP meets these requirements through the following features:
(1) Extreme Temperature Resistance: With a melting point of 3410°C, the tungsten heater maintains excellent structural strength under high temperature conditions, ensuring the stability of the process temperature zone.
(2) High Vacuum Compatibility: In high vacuum or inert gas environments, the vapor pressure of tungsten remains extremely low. It prevents oxidation or carburization of the workpiece surface caused by element volatilization, preserving surface cleanliness.
(3) Uniform Thermal Field Distribution: Through precise control of helical pitch and resistance matching, a constant radiant thermal field is established within the heat treatment chamber. It ensures uniform heating of the workpiece, enhancing the consistency of its microstructural properties.
(4) Fatigue Resistance and Longevity: By optimizing the grain structure of the tungsten wire, the heater achieves good anti-sag and creep resistance. It remains resistant to brittle fracture during frequent thermal cycling, significantly reducing equipment maintenance costs.
CTIA GROUP provides high-performance specifications tailored for industrial heat treatment environments:
Material: High-purity tungsten wire (purity ≥ 99.95%) or doped tungsten wire.
Wire Diameter: 0.8~2.0mm.
