Feature | Advantage |
High Temperature Resistance | Tungsten-copper alloy has a high melting point, can withstand extreme working temperatures, and is not easy to deform or wear. |
Excellent Electrical Conductivity | The copper matrix provides a low-resistance path to ensure efficient power transmission. |
Outstanding Heat Dissipation | The high thermal conductivity of copper (401W/m·K) quickly dissipates arc heat and prevents electrode overheating. |
Arc Erosion Resistance | The tungsten-copper interface forms a "sweating cooling" effect, extending the electrode life by 3-5 times. |
High Strength and Wear Resistance | The high hardness of tungsten (≥300HV) prevents the electrode head from deforming easily, making it suitable for high-pressure welding environments. |
Low Expansion Coefficient | Reduces thermal deformation and ensures processing accuracy and stability. |
Cooling channel: The through-hole design allows the circulation of cooling media (water, oil), greatly improving heat dissipation efficiency, which is especially suitable for high-power continuous operations.
2. Chip/Exhaust channel: In electrical discharge machining (EDM), the holes help discharge machining chips and gases, prevent secondary discharge, and improve processing accuracy and efficiency.
3. Fluid handling: Can be used as a transmission channel for liquids or gases in special applications.
4. Weight and material saving: Reduces weight while ensuring structural strength, lowering material costs.
Spot welding and projection welding electrodes: Suitable for welding difficult-to-weld materials such as stainless steel and aluminum alloy, extending the electrode life by more than 50%.
Seam welding roller electrodes: Used for continuous welding of metal plates. The open-hole design enhances the cooling effect and extends the roller life.
Nut welding: Particularly suitable for high-strength connection between nuts and plates in the automotive industry.
Deep hole machining electrodes: The open-hole design provides a chip discharge channel, reducing "secondary discharge" and improving the accuracy and efficiency of deep hole machining.
Precision mold machining: The electrode has little wear and can achieve mirror-level machining results.
Special-shaped electrodes: Can machine complex three-dimensional structures that are difficult to achieve with traditional electrodes.
Plasma spraying electrodes: Their high-temperature resistance makes them key components of plasma equipment.
High-voltage discharge tube electrodes: Resistant to arc erosion, suitable for high-voltage and high-frequency discharge environments.
Electronic packaging: Used as heat dissipation electrodes for high-power semiconductor devices.
