Tungsten electrode is a commonly used metal electrode material with many excellent physical properties. The following are some of the main physical properties of tungsten electrodes.
Density: Tungsten has a very high density of approximately 19.3 grams per cubic centimeter, making it one of the densest metals in nature.
Melting point: Tungsten has a very high melting point, approximately 3422 degrees Celsius (6192 degrees Fahrenheit). This allows tungsten electrodes to maintain stability and durability in high temperature environments.
Thermal Conductivity: Tungsten has good thermal conductivity, approximately 174 W/m·Kelvin. This allows the tungsten electrode to conduct heat efficiently while providing good thermal stability for high temperature applications.
Linear expansion coefficient: The linear expansion coefficient of tungsten is about 4.5 x 10^(-6) K^(-1), which means that the dimensional change of the tungsten electrode when the temperature changes is relatively small.
Electrical Conductivity: Tungsten has a relatively high electrical conductivity, around 18-30 MS/m (megasiemens/meter). This allows tungsten electrodes to provide good electrical conductivity properties in electronic devices and power applications.
Mechanical Properties: Tungsten has excellent mechanical properties, including high strength, excellent corrosion resistance and oxidation resistance. This allows the tungsten electrode to operate in harsh environments for long periods of time without being easily damaged.
Overall, tungsten electrodes are widely used in various fields such as arc welding, EDM, smelting, optical equipment, and electronic devices due to their high melting point, good thermal and electrical conductivity, and excellent mechanical properties. . These physical properties make tungsten electrodes ideal for many high temperature and high performance applications.
