What Is a Graphite Electrode?
A graphite electrode is an electrode primarily composed of a sintered body made from carbon-containing powder.
This type of electrode possesses several outstanding characteristics. Firstly, it exhibits excellent conductivity, allowing for efficient electricity conduction. Additionally, it boasts high heat resistance, mechanical strength, and corrosion resistance.
Graphite electrodes find their main applications in electrical discharge machining for mold and part processing, metal welding, laser processing for both metal and plastic processing, and electrochemical devices such as batteries and fuel cells. There are also various types of graphite electrodes available. Isotropic graphite electrodes feature a uniform crystal structure and are employed in electrical discharge machining and welding applications. On the other hand, anisotropic graphite electrodes have a crystal structure that varies with direction and are utilized in laser processing and electrochemistry.
