When selecting the graphite electrode material

In order to ensure the quality of the graphite electrode, it is necessary to ensure that the graphite electrode material is qualified, but what problems should be considered when selecting the graphite electrode material?

1. The average particle diameter of the graphite electrode material, the diameter of the particle will directly affect the discharge state of the graphite electrode material. The smaller the particle, the more uniform the discharge, the more stable the discharge condition, and the better the surface quality of the graphite electrode. Conversely, the larger the particle, the faster the discharge and the lower the loss of roughing. Mainly because the current intensity of the discharge process is different, the energy of the discharge is different. However, the surface finish after discharge also changes with the change of the particles.

2. The flexural strength is a direct reflection of the strength of the graphite electrode material and shows the tightness of the internal structure of the material. The graphite electrode material with high strength has relatively good loss resistance performance, and for electrodes with high precision, try to select materials with better strength.

3. When the average particle size of the graphite electrode material is the same, the discharge rate with a large resistivity will be slower than the resistivity. For materials of the same average particle size, materials with low resistivity will have a slightly lower strength and hardness than materials with high resistivity. That is, the speed of discharge will vary. Therefore, it is very important to select materials according to the needs of the actual application.

If you still can't make your choice on select graphite electrode material,just go and ask manufacturer directly such as zhouhua carbon,they have help me a lot.
