Tungsten Copper Electrodes

tungsten copper electrodes

tungsten copper electrodes In the long period of time when EDM began, copper and copper alloys were generally used as machining electrodes. Although copper and copper alloys are cheap and easy to use, copper and copper alloy electrodes are not resistant to spark erosion, resulting in large electrode consumption and poor machining accuracy (sometimes multiple machinings are required). With the continuous increase of mold precision and the amount of many difficult-to-machine material components, as well as the increasing maturity of EDM technology, the amount of tungsten copper materials used as EDM electrodes is increasing day by day. The electric machining electrode using tungsten copper material not only improves the precision of the processed molds and components, but also has small electrode loss and high processing efficiency, and can even complete the roughing and finishing of the product at one time. EDM electrodes are characterized by a wide variety of specifications, small batches, and large totals. The tungsten-copper material used as an electric machining electrode should have the highest possible density and uniformity of structure, especially for some slender rods, tubes, and special-shaped electrodes. If the conventional method is used, the process is very complicated and the material Utilization is low.

Resistance welding electrodes :

Combining the good properties of tungsten and copper, high-temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical and thermal conductivity, ease of the process, and its functions such as sweating, high hardness, high melting point, and anti-adhesion of tungsten. Features are often used to make certain wear resistance, high and low-temperature welding, and butt welding electrodes.
