Below is Copper tungsten alloy electric spart electrodes.
Copper tungsten alloy products are used for electric spark electrodes:
When molds made of tungsten steel and high-temperature resistant superhard alloys require electrical corrosion, ordinary electrodes have high losses and slow speeds. And tungsten copper has a high corrosion rate and low loss rate,
The precise electrode shape and excellent processing performance of copper tungsten alloy can greatly improve the accuracy of the workpiece being processed.
Electric discharge is a machining process that primarily utilizes discharge electrodes (EDM electrodes) with specific geometric shapes to burn out the geometric shape of the electrodes on metal (conductive) components. Copper tungsten alloy is an ideal electrode for electrical discharge. Electric discharge machining technology is commonly used in the production of punching molds and casting molds.
Utilizing the corrosion phenomenon generated during copper tungsten alloy spark discharge for dimensional machining of materials, it is a spark discharge in a liquid medium within a lower voltage range. Electrical discharge machining is mainly completed by mechanical factories, which burn the desired geometric shapes on metal components through local corrosion.
