Tungsten copper alloy has a wide range of uses, mainly used in the manufacture of arc ablative resistance of high voltage electrical switch contacts and rocket nozzle throat liner, tail rudder and other high temperature components, also used for electrical processing electrodes, high temperature mold and other requirements of conductive and thermal conductivity and high temperature applications.

Resistance welding electrode (choose tungsten copper WD10080) : It integrates the advantages of tungsten and copper, such as high temperature resistance, arc ablation resistance, high strength, high ratio, good conductivity, good thermal conductivity, easy machining, and has the characteristics of cold sweat, because of the high hardness of tungsten, high melting point, anti-adhesion characteristics, often used to do a certain wear resistance, high temperature resistance of convex welding, butt welding electrode. Spark electrode (choose WD10070, WD10075, discharge tungsten steel should choose WD10080) : For the tungsten steel, high temperature resistant superhard alloy made of the mold needs electrical corrosion, the ordinary electrode loss is large, slow, and tungsten copper high electrical 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 (choose WD10070) : When the high voltage vacuum discharge tube is working, the temperature of the contact material will rise several thousand degrees Celsius within a few tenths of a second. The tungston-copper corrosion resistance, high toughness, good electrical and thermal conductivity properties provide the necessary conditions for the stable operation of the discharge tube.
