What’s Ablation Tungsten Electrode?
What’s Ablation Tungsten Electrode?
Ablation tungsten electrode, also known as micro tungsten needle ablation electrode, is a high-performance discharge electrode made from high-purity tungsten or rare-earth-doped tungsten. It is designed for high-frequency, radio-frequency, or plasma energy environments and used with high-frequency electrosurgical systems. Through strong electric field concentration at the tip, it enables localized high-energy output for precise material or tissue ablation.
Advantages of CTIA’s Ablation Tungsten Electrode
CTIA’s ablation tungsten electrode delivers stable and reliable performance in high-energy applications:
(1) High Melting Point Stability: Melting point about 3420°C, suitable for long-term high-temperature discharge environments
(2) Excellent Ablation Resistance: Reduces tip wear and extends service life
(3) Stable Electron Emission: Ensures consistent arc ignition and maintenance
(4) High Dimensional Stability: Maintains geometry under cyclic loading
(5) Low Contamination: Reduces impurity migration and improves system cleanliness and safety
In medical and high-end industrial applications, it enables millimeter or even sub-millimeter precision control.
Working Principle of CTIA’s Ablation Tungsten Electrode
The working mechanism is based on combined effects of high electric field concentration, localized thermal effect, and plasma action:
(1) Under high-frequency or Direct Current (DC) electric fields, a high current density region forms at the electrode tip
(2) Enhanced electron emission generates localized plasma discharge
(3) Energy rapidly converts into heat, causing vaporization or structural decomposition of the target material
(4) Controlled energy density enables precise micro-area ablation while minimizing thermal diffusion
In Radio Frequency Ablation (RFA) systems, tungsten electrode serves as the core energy delivery component.
