High density: The density of graphite electrodes is high, which can ensure their strength and hardness, and can also improve their electrical conductivity and thermal conductivity.
High strength: Graphite electrodes have high tensile strength and compressive strength and can be used in high temperature and high pressure environments.
High conductivity: Graphite electrodes have excellent electrical conductivity and can be used to manufacture electronic products such as electrodes and wires.
