Application scope of tungsten copper plate

Tungsten copper plate combines the advantages of metal tungsten and copper. Among them, tungsten has a high melting point and high density. The melting point of tungsten is 3410 degrees Celsius, and the melting point of copper is 1083 degrees Celsius. Copper has excellent electrical and thermal conductivity. Uniform microstructure, high temperature resistance, high strength, arc ablation resistance, high density, moderate electrical and thermal conductivity, are widely used in high temperature resistant materials, electrical alloys for high voltage switches, electrical machining electrodes, microelectronic materials, as parts and components And components are widely used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries.
A very important application of tungsten copper plate is as the electrical contact of high-voltage electrical switches. The electrical contact material is also called contacts or contacts. It is the key component of high and low-voltage electrical appliances and is responsible for making and breaking current. , which directly affects the reliability and service life of switches and electrical appliances.
For a long time since the development of EDM, copper or copper alloys were generally used as machining electrodes. Although copper and copper alloys are cheap and easy to use, because copper and copper alloy electrodes are not resistant to spark ablation, the electrodes The consumption is large, the machining accuracy is poor, and sometimes multiple processing is required. With the increasing mold accuracy and the amount of many difficult-to-machine material components, and the increasing maturity of the EDM process, the amount of tungsten copper plate used as an EDM electrode Increasingly, at present, it can be used as electrode materials such as resistance welding electrodes, EDM electrodes, plasma electrodes, etc. In the process of EDM, the role of electrode materials is to deliver processing pulses and remove workpieces with minimal loss.
