Tungsten copper alloy has a broader purpose is mainly used to make contacts and rocket nozzle throat, rudder and other high-temperature components of high-voltage electrical arc erosion resistant switches, also used as EDM electrodes, dies and other high-temperature requires high-temperature thermal conductivity properties and occasions for use. Fine selection of tungsten copper tungsten, copper powder, soaked by the first-class sintering process is refined, and can withstand high temperature and high stress nearly 2,000, with a high melting point, high hardness, resistance to burning and good anti-adhesion, electrical erosion surface finish high, high precision, low loss. Tungsten Copper is widely used as high-voltage, ultra-contact switches and hydraulic breakers, protection ring, electric upsetting anvil material for conductive Tsui automatic submerged arc welding, plasma cutting machine nozzle, welding machine, welding machine welding head , seam welding wheels, air sealing point sockets spark electrode and the electrode, spot welding, butt welding materials. Tungsten Copper is an excellent use of high-purity tungsten metal powder of high purity copper powder characteristics and plasticity, high electrical conductivity, etc., by isostatic pressing, sintering temperature, dissolved copper refining process infiltration of composite materials. Broken arc performance, good thermal conductivity, low thermal expansion, high temperature softening, high strength, high density, high hardness. Tungsten copper alloy has a broader purpose is mainly used to make contacts and rocket nozzle throat, rudder and other high-temperature components of high-voltage electrical arc erosion resistant switches, also used as EDM electrodes, dies and other high-temperature requires high-temperature thermal conductivity properties and occasions for use. Resistance welding electrode resistance welding electrodes (select tungsten copper WD10080): combines the advantages of tungsten and copper, high temperature resistance, electric arc ablation, high-intensity, heavy, electrical conductivity, thermal conductivity, ease of machining, and with sweating Coolers other characteristics, due to the high hardness, high melting point, tungsten has anti-adhesion characteristics, often used for a certain wear resistance, high temperature welding, welding electrodes. EDM electrode EDM electrodes (select tungsten copper WD10070, WD10075, discharge tungsten steel should choose WD10080): tungsten steel, when the high temperature super-hard alloy die to be galvanic corrosion, the common electrode wear big, slow, and tungsten-copper corrosion, high speed, low loss rate, the exact shape of the electrode, excellent processing performance, to ensure the accuracy of the workpiece are greatly improved. High voltage discharge electrode high voltage discharge electrode (select WD10070): high-voltage vacuum discharge tube at work, contact material time within a few tenths of a few thousand degrees Celsius temperature, while the tungsten and copper ablation resistance, high toughness, , good electrical conductivity, thermal conductivity to discharge stable job to provide the necessary conditions.
