2015/10/6Nowadays, graphite is one of the most popular electrode materials in electrical discharge machining (EDM) processes due to the high rate of removal material which reduces machining times. This reduction has a direct impact on the cost of manufacturing the parts. In this research, the influence of EDM parameters and graphite electrode in an INCONEL 600 alloy has been studied for both

Graphite Electrode Market, Size, Share

The global graphite electrodes market was valued at USD 3.89 billion in 2018, and is projected to reach USD 5.85 billion by 2026, growing at a CAGR of 5.5% from 2020-2027. Graphite electrodes are a vital input for electric arc steel-making and ladle refinement of steel, as well as play an essential role in the automotive industry.

Five reasons to use graphite EDM electrodes –

EDM Performance EDM operators know that excessive wear results in the use of extra electrodes or frequent redressing. Graphite is able to achieve electrode wear of less than 1% in relation to the depth of cut, while working to more aggressive machine

The advantage of Graphite Electrodes : u/raycarbon20

In addition, some special shaped electrodes can not be made of copper, but graphite is easier to form, and copper electrode is heavier, which is not suitable for processing large electrode. These factors cause some group based spark machine customers to use graphite electrode.
