Qingdao Zhonghe Carbon Products Co., Ltd. can not only produce and provide different types of graphite electrodes according to user needs, but also provide graphite electrode materials, and the quality of graphite electrode materials will directly affect the quality of graphite electrodes. Therefore, when producing graphite electrodes, the quality of graphite electrode materials must be strictly controlled. The following will mainly introduce the characteristics of graphite electrode materials.

1. Fast speed. Graphite discharges 2-3 times faster than copper. Data is not easy to deform. It has obvious advantages in the processing of thin rib electrodes. The softening point of copper is around 1000 degrees, which is simply deformed by heating. Graphite increases the temperature. It is around 3650 degrees. In comparison, the thermal expansion coefficient of graphite materials is only 1/30 of that of copper materials;

2. Light weight, the density of graphite is only 1/5 of that of copper. When large electrodes are used for electrical discharge machining, they can effectively reduce the burden of machine tools (EDM) and are more suitable for the use of large molds;

3, the loss is small, because the spark oil contains C atoms. During electrical discharge machining, the high temperature causes the C atoms in the spark oil to be decomposed, and a protective film is formed on the surface of the graphite electrode to compensate for the loss of the graphite electrode;

4. No burrs. After the copper electrode is processed, it needs craftsmanship to remove burrs, while the graphite electrode has no burrs after processing. This not only saves a lot of cost and manpower, but also completes automated production more easily;

5. Easy to polish, because the cutting resistance of graphite is only 1/5 of that of copper, it is easier to perform manual grinding and polishing in operation;

6. The cost is low, because the quotations of copper materials have been rising in recent years. Now, the quotations of the same-sex graphite in all aspects are lower than those of copper; the universality of Toyo Carbon under the same volume, the quotation of graphite products is 3% lower than that of copper Ten to sixty, the quotation is relatively stable, and short-term quotation fluctuations are relatively small.

Due to the limited time, only the characteristics of graphite electrode materials are introduced.
