Dia 25mm WCu20 Tungsten Copper Alloy Rod Bright Surface For Electrodes
1. Description of Copper Alloy Rod Tungsten Copper Alloy For Electrodes :
The excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder are combined to create tungsten copper, a composite material that is refined through the processes of static pressing, high temperature sintering, and copper infiltration. Good electrical and thermal conductivity, low thermal expansion, little softening at high temperatures, high strength, high density, and high hardness are all characteristics that contribute to effective arc breaking.

4.Application of Copper Alloy Rod Tungsten Copper Alloy For Electrodes :
Resistance welding electrodes
Combining the good properties of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, large specific gravity, good electrical and thermal conductivity, easy to process, and its functions sweating, for instance, or tungsten's high hardness, high melting point, and anti-adhesion features, which are frequently employed to ensure wear resistance, high and low temperature welding, and butt welding electrodes.
EDM electrode
The accuracy of the workpiece is greatly improved by using tungsten copper electric, which has a high speed, low loss rate, precise electrode shape, and excellent machining performance corrosion in comparison to tungsten steel, a high temperature resistant super hard alloy die-casting that is produced by corrosion.
High Voltage Discharge Tube Electrodes
In the workplace, the high-voltage vacuum discharge tube briefly makes contact with the material at 0 and thousands of degrees Celsius, and its ablation resistance, high toughness, and good electrical conductivity are all demonstrated the tungsten copper's electrical and thermal conductivity offers the discharge tube's required stable circumstances.
Electrical Sealing Materials
It not only possesses the high thermal conductivity and low expansion of tungsten and copper. Its expansion index and thermal conductivity can also be changed by changing the content of the material, providing convenience for the use of material.We can supply tungsten-tungsten-copper alloys of various specifications and different proportions.
