Tungsten Copper Rod Application
Tungsten copper is the use of high-purity tungsten metal powder excellent characteristics and plasticity, high conductivity copper powder of high purity, etc., by isostatic pressing, high temperature sintering, melting refined copper infiltration process of composite materials. Breaking arc performance, good thermal conductivity, low thermal expansion, high temperature does not soften, high strength, high density, high hardness.
Tungsten copper uses include the following
1.Resistance welding electrode: combines the advantages of tungsten and copper, high temperature resistance, arc ablation, high intensity, than the major, conductive, thermal conductivity, easy cutting, and has features such as transpiration cooling, due to the high having tungsten hardness, high melting point, anti-adhesion characteristics, often used to do a certain wear resistance, high temperature projection welding, butt welding electrode. Tungsten copper used to make the ratio of resistance welding electrode materials generally used 80W20Cu.
2.EDM electrode: tungsten steel, high temperature super-hard alloy die to take electrical erosion, ordinary electrode wear big, slow, and tungsten and copper corrosion, high speed, low loss rate, precise electrode shape, excellent processing performance, to ensure the accuracy of the workpiece is greatly improved. Tungsten copper EDM electrodes used to make the ratio of tungsten and copper is generally used 75W25Cu 70W30Cu and materials, and the discharge tungsten steel selection 80W20Cu.
3.High-voltage discharge electrode: high-voltage vacuum discharge tube at work, the contact material in a fraction of a second temperature rises several thousand degrees Celsius, while tungsten and copper ablation resistance, high toughness, good electrical and thermal conductivity discharge stable performance to provide the necessary conditions.
