Tungsten Copper Electrode

Tungsten copper electrode is a metal electrode whose material components are tungsten and copper. In the case of their alloys, the maximum temperature can reach 3,400 degrees. Therefore, such electrodes are commonly used in high-temperature applications such as gas discharge tubes, arc machining, resistance welding, electrical discharge machining, etc. Cu-W electrodes have good electrical, thermal, and mechanical properties, as well as corrosion resistance, making them ideal for many applications.

The copper tungsten electrode is a composite material composed of pure copper and tungsten, which has excellent physical properties.

• Density: The density of it is between 14.5-15.0g/cm3, which is a high-density material.
• Thermal conductivity: Both copper and tungsten are good thermal conductivity materials, and the tungsten electrode made of the two composites has good thermal conductivity.
• Conductivity: Copper is a good conductive material, and copper tungsten electrodes have high conductivity.
• Wear resistance: Tungsten has high hardness and wear resistance, and the hardness and wear resistance of it is also relatively high.
• Corrosion resistance: It has good corrosion resistance and can resist most acids, alkali's, and salt water.
• Coefficient of thermal expansion: The thermal expansion coefficient of copper tungsten electrodes is similar to that of steel, which can be well matched with other materials.

The above are the physical properties of copper tungsten electrodes.

1) High-temperature resistance: It can withstand long-term use at high temperatures.

2) Corrosion resistance: It has excellent corrosion resistance and can resist the erosion of various chemicals.

3) Conductivity: Since tungsten is an excellent conductive material, the conductivity of it is very good.

4) Wear resistance: It has good wear resistance and are not easily damaged, which can reduce the frequency of electrode replacement.

5) Reasonable cost: Compared with pure tungsten electrodes, the price of it is relatively reasonable, and it has good performance

1) First, mix copper and tungsten powder in a certain proportion;

2) Then, the mixed powder is pressed into shape;

3) Then, sintering is carried out at high temperature, so that copper and tungsten are evenly combined to form a hard alloy;

4) Finally, it is processed into the required shape and size by machining and polishing.

In terms of working principle, tungsten copper electrode mainly utilizes its high hardness and high thermal stability, so that it can maintain a stable shape under high temperature and high-pressure environment, and has good conductivity to the heat and current of the arc. This makes it suitable for applications such as arc machining and spot welding at high temperatures. At the same time, its corrosion resistance prevents the electrodes from being corroded and damaged in chemical environments.

Copper-tungsten electrode is a commonly used unconventional electrode material, which is composed of high-purity copper and tungsten metal materials.

Tungsten copper electrode is usually packed in plastic tubes or cartons to protect from moisture and contamination. During transportation, bumps and extrusions should be avoided to prevent electrodes from being lost or broken. It is recommended to store electrodes separately from other items to avoid wear and cross-contamination. When storing and using white tungsten electrodes, relevant safety operating procedures should be followed to ensure the safety of personnel and equipment.

The working principle of copper tungsten electrode depends on its material properties, it has the advantages of high density, high melting point, low thermal expansion coefficient, high electrical conductivity, and so on. These properties make copper tungsten electrodes an excellent choice for high-temperature, high-frequency applications.

Tungsten copper electrodes are often used in the electronic processing industry, such as laser welding, EDM, electron beam processing, and other fields. These applications require high-performance electrodes because the processes require high-frequency, high-energy electrodes to treat molds and workpieces. Copper tungsten electrodes are a premium choice due to their properties such as high density, high wear resistance, and high electrical conductivity.
