Market Overview The graphite electrodes market was valued at USD 4,431.49 million in 2020, and the market is projected to register a CAGR of over 6.5% during the forecast period (2021-2026). The primary raw material used for the production of graphite electrodes is needle coke (either petroleum-based or coal-based).
Graphite Electrode Market | 2021 - 26 | Industry Share, Size ...
The sublimation temperature of graphite is 3650 degrees, and the thermal expansion coefficient is only 1/30 of copper. Lightweight. The density of graphite is only one-fifth of copper. The use of EDM to process large electrodes can effectively reduce the burden on the machine tool. Less Consumption in the Discharge Process
Is Graphite a Substitute For Copper As a Discharge Material?
The butt consumption of the electrode is mainly caused by sublimation of graphite at high temperature and melting in steel slag. In normal operation, the butt consumption can reach 50% of the total electrode consumption. Side consumption is the main reason why the electrode is oxidized. The consumption is about 40% of the total consumption.
What is the market size of the graphite electrode market for ...

isostatic graphite is used in EDM Machining and better than copper electrode.The proportion of graphite is 1/5 of the copper,the weight of the same volume of graphite is relatively light for 5 times of copper,which is easy to make large die mold.the graphite processing speed is generally 3-5 times faster than ordinary metals,which can reduce the tool wear and electrode consumption.Graphite is high melting point and not easy transformed,so don't have to worry about deformation and damage of ...
