Resistance welding electrode, electric spark electrode

Tungsten copper alloy electrode is a composite metal material made of high purity tungsten powder and high conductivity copper powder with good purity and plasticity, through static pressure molding, high temperature sintering and melting process. It has the characteristics of good conductivity, small thermal expansion, no softening at high temperature, high strength, high density, high hardness and so on.
resistance welding electrode
Resistance welding electrode combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, specific gravity, electrical conductivity, good thermal conductivity, easy cutting, and has the characteristics of sweating and cooling, due to the high hardness of tungsten, High melting point, anti-adhesion characteristics, often used to do a certain wear resistance, high temperature resistance of projection welding, butt welding electrode.
EDM electrode
EDM electrodes early copper or graphite electrodes, cheap but not resistant to ablation. The advantages of tungsten copper electrode are high temperature resistance, high temperature strength, arc ablation resistance, good electrical and thermal conductivity, and fast heat dissipation. Applications focus on electric spark electrodes, resistance welding electrodes and high-voltage discharge tube electrodes. Electrical processing electrode is characterized by a wide variety of specifications, small batch and total. The tungsten-copper material used as an electromachining electrode should have the highest possible density and uniformity of tissue, especially elongated rod-shaped, tubular and special-shaped electrodes. Tungsten-copper alloy for EDM electrode In the long period of development of EDM, copper and copper alloy are widely used as processing electrode. Although copper and copper alloys are inexpensive and easy to use, copper and copper alloy electrodes are not resistant to electric spark ablation, resulting in large electrode consumption and poor machining accuracy (sometimes multiple machining is required). With the increasing precision of the mold and the amount of many difficult-to-process materials, as well as the increasing maturity of the EDM process, the amount of tungsten copper materials as EDM electrodes is increasing day by day. The use of tungsten-copper electromachining electrodes not only improves the accuracy of the processed molds and components, but also has low electrode loss and high processing efficiency, and even the roughing and finishing of the product can be completed at one time. EDM electrode is characterized by a wide variety of specifications, small batch and large total. In particular, some slender rods, pipe materials and special-shaped electrodes, if the regular method is used, the process is very complicated, the material utilization rate is very low.
Electric spark electrode for tungsten steel, high temperature resistant super hard alloy production of mold need electric corrosion, ordinary electrode loss, slow speed, and tungsten copper high electric corrosion speed, low loss rate, accurate electrode shape, excellent processing performance, can ensure that the accuracy of the workpiece is greatly improved.
high voltage discharge tube electrode
High voltage vacuum discharge tube in the workplace, in a few seconds of time contact material zero thousands of degrees Celsius, and tungsten copper ablation resistance, high toughness, good electrical and thermal conductivity can provide the necessary conditions for the stability of the discharge tube.
