Resistance welding electrode (WD10080): it synthesize the advantages of tungsten and copper, such as high temperature resistance, resistance to arc erosion, high strength, large conductivity, good thermal conductivity, easy machining, because it has the characteristics of tungsten, such as high hardness, high melting point, anti adhesion, it often is used to do some resistance welding of high temperature, the welding electrode.
EDM electrode (tungsten copper WD10070, WD10075 discharge should choose WD10080 tungsten steel)；when the mould made of tungsten steel, super hard alloy is galvanic corrosion, the loss of common electrode is large, while the tungsten copper with high electric corrosion, low loss rate, precise electrode shape, excellent processing performance, can guarantee the processing accuracy is greatly improved.
High pressure discharge tube electrode (WD10070): when the high voltage vacuum discharge tube is working, the temperature of contact materials will raise several thousand degrees Celsius at a few tenths of the time, and the tungsten copper with ablative properties, anti high toughness, good electrical conductivity, thermal conductivity can provide necessary conditions for discharge tube.
Its main chemical composition: Tungsten W 70%, copper Cu 30%.Application: Resistance welding electrode, spark electrode, high voltage discharge tube electrode, electronic packaging material. Physical and mechanical properties: density 13.8-14 g/cm3, Conductivity: 42, hardness: 185HV, Bending strength Mpa: 700, Softening temperature ℃: 900.
