Copper Tungsten Electrode

Copper Tungsten Electrode is an electrode made from a copper-tungsten alloy, also called pseudo-alloy, which may be better described as a composite material since it has a metal matrix structure instead of being a real alloy.

The type of these electrodes is created through a isostatic pressing, high-temperature sintering, followed by melting copper to form refined copper. This process takes full advantage of the plasticity and high conductivity of pure tungsten.

Copper Tungsten Electrode has a predominant application within the petroleum and natural gas industry, as well as within the engine, electric power, electronics, metallurgy, aerospace sectors, and are often employed in electrical discharge machining (EDM) and electrochemical machining (ECM).

Because of Copper Tungsten Electrodes, wire and rod cross welding is possible of large diameters. It also has the capability of being used as a copper tungsten heat sink for cooling certain elements of electronic devices. In the motor and automotive industries, these electrodes are used in high-speed, automated spot welding of wire harnesses. In addition, these electrodes can be used for the spot welding of ferrous metals such as stainless steel and low-conductivity ferrous metals.

Compared to conventional electrodes, copper tungsten electrodes have a high corrosion rate relative to loss rate which impacts the precision of parts that are machined.

1. Electrical and thermal conductivity: Copper-tungsten Electrode encompasses both the thermal conductivity of tungsten and the conductivity copper possesses (≥80%IACS) which is high. This makes its use appropriate during high current and high-frequency electrical processing situations such as in electric spark processing and resistance welding.

2. High temperature and arc ablation resistance: Tungsten possesses a high melting point at 3410°C while copper has a 'sweating cooling' effect thus, this combination enables the alloy to withstand high degree current, arc impacts, and render it effective in high-grade electrical processing environments.

3. High hardness and wear resistance: The combination gives the electrode excellent wear resistance due to tungsten possessing high hardness (≥ 60 HRC) thus making them suitable for high load and frequency electrical processing, achieving decreased wear.

1. Copper tungsten electrodes serve to produce precise molds and blades for aircraft engines that are complex in design to improve accuracy in processing and enhance the quality of the surface.

2. They are used in the production of cars, as well as in the welding of electronic components. Also, they allow advanced metals such as copper and aluminum to be utilized in both spot welding and roller welding where vigorous electrical currents flow.

3. To preserve the reliability and safety of the apparatus, copper tungsten electrodes are employed in the manufacturing of surgical instruments, electrical stimulators, some connectors, relays, and switches.
