Tungsten electrodes exhibit compelling advantages over other electrode materials, properties that make them the preferred choice for high-temperature, high-energy environments. First of all, tungsten has an extremely high melting point, reaching 3422 degrees Celsius, which allows it to maintain stability in extremely high-temperature environments and is not easy to melt, making it suitable for various high-temperature processes and applications.
The low evaporation rate of tungsten electrodes is one of its unique properties. In high-temperature environments, tungsten does not easily evaporate into gas, which helps maintain the shape and size of the electrode, thereby extending its service life. This also makes tungsten electrodes perform well in high-energy applications and are suitable for scenarios that require long-term, high-intensity work.
Good electrical conductivity is another reason for the popularity of tungsten electrodes. As an excellent conductive material, tungsten has high electrical conductivity, ensuring that current can be conducted stably in the electrode, providing a reliable arc for welding, cutting and other applications.
Oxidation resistance is one of the key properties of tungsten electrodes to keep their surfaces clean in high-temperature environments. Because tungsten is not easily oxidized, it maintains high oxidation resistance, helping to improve the stability and durability of the electrode. This makes tungsten electrodes perform well in scenarios that require long working hours and require high arc stability.
In addition, tungsten electrodes have good chemical stability and are not easily corroded by many chemical reactions, which provides greater flexibility for their application in different environments. Its low thermal expansion coefficient also helps reduce dimensional changes caused by temperature changes and maintain electrode stability.
The high strength of tungsten electrodes makes them less likely to soften or deform in high-temperature environments, which helps maintain structural stability. Taken together, due to these excellent properties, tungsten electrodes are widely used in arc welding, plasma cutting, optoelectronics equipment and other fields, making them an ideal choice in many high-energy and high-temperature scenarios.
