Product Code : AL-WCu-90W10Cu-CU
Tungsten copper electric spark electrode is a two-phase structure pseudo alloy composed of tungsten element as the base and copper element as the auxiliary. It is made of fine high-purity tungsten powder and high-purity tungsten copper powder by the first-class process of mixed powder hydrostatic forming high-temperature sintering solution copper. Tungsten-based composites are strong refractory metal materials manufactured by a strictly controlled process including pressing, sintering and infiltrating with copper. The properties of Tungsten composites are influenced by the copper-to-Tungsten ratio. If the Tungsten content improves, the electric arc and wear resistance will increase while the thermal and electrical conductivity, on the contrary, will reduce. but also arc corrosion resistance, high wear resistance, long service life and low correction electrode rate. So it is an ideal advanced electrode material.

Applications of Tungsten Copper Alloy Electrode
Tungsten-Copper electrodes are suited to a wide range of high-speed, automated welding operations. For brazing copper and copper alloys, Tungsten-Copper electrodes offer excellent electrode heat balance for applications such as high-speed spot welding of wire harnesses for use in motors, automobiles, and anywhere complex or simple wire harnesses are used. Other applications include line switches for battery packs, as well as electrical components for manufacturing lines of circuit breakers and electrical switches. Tungsten copper alloy electrode has the advantages of high electric corrosion rate, low loss rate, precise electrode shape, excellent processing performance, and good surface quality of processed parts. As parts and components, it is widely used in aerospace, aviation, electronics, power, metallurgy, machinery, medical equipment and other industries. It can be used for the EDM electrode and Resistance welding electrode. EDM electrode (electrical discharge machining, EDM) can be made of the tungsten copper alloy, which has the advantages of high conductivity, high melting point and small thermal expansion. In the EDM process, the electrode is used to transmit the machining pulse and etch the workpiece with its own minimum loss. Because of its excellent machining performance, EDM can effectively save electrode materials, improve the speed of EDM and improve the accuracy of die, and thus save the cost of machining tools and maintenance costs.
Packing of Tungsten Copper Alloy Electrode
