Advantages Of Graphite Electrode Material

Nowadays, due to the rising price of copper in recent years, graphite electrode has been developed rapidly. The price of graphite electrode is 30%~60% lower than that of copper, and the price is
relatively stable.

Graphite discharge than copper 2-3 times faster, not easy to deformation, processing advantages.In terms of temperature, the softening point of copper is about 1000℃, which is easy to be deformed due to excessive heat, while the temperature of graphite is 3650℃.In contrast, the thermal expansion coefficient of graphite electrode is only 1/30 of that of copper. Moreover, the graphite electrode can effectively reduce the burden of machine tools, and the density is only 1/5 of that of copper, which is more suitable for the application of large mold.

During discharge machining, the C atoms in the spark caused by the high temperature are decomposed, and the graphite electrode forms a maintenance film on the surface to make up for the loss of the graphite electrode.After the copper electrode is processed, it still needs to deburr manually, while the graphite is processed without burr, which not only saves a lot of labor and time, but also makes it easier to realize automatic production.

The cutting resistance of graphite electrodes is only 1/5 of that of copper, which makes it easier to grind and polish by hand.The graphite electrode has good processability and can achieve complex geometric modeling, light weight, small density, good thermal stability, no deformation and no processing burr, and can reduce the number of individual electrodes and be bundled into composite electrodes.
