Why Graphite is a preferred material for EDM electrodes?

It is estimated that 70 percent of the world’s industrial market prefers to use Graphite for EDM electrodes, unlike the previous times when copper was the most popular material for the EDM. The reason is that Graphite has myriad benefits to serve.

Graphite Electrode Cost

Graphite is very economical as compared to copper. Those who think that copper is economic are actually comparing the price of copper with the highest quality of exclusive Graphite. But the fact is Graphite has a wide variety with different prices. Most Graphite is quite cheaper than copper. Also, Graphite offers fast production time to create electrodes as well as efficient machining, which eventually saves the overall cost. While the gummy material of copper makes the production process slower. 

Material Variety

The wide range of Graphite available has the ability to contour itself according to the properties of the electrode material. Graphite can also fit the requirements of an extremely detailed EDM with crucial features, tolerance, and strict EDM for any application. 

Electrode Detailing

The Graphite can work well at high-current density and allows complex machined details to be designed on the same electrode. As there is a huge variety of Graphite available, one can choose it according to their preference of surface finishing, electrode life, speed of cut, and metallurgy of the task.

Surface Finishing

The Graphite can offer the same surface finishing as the copper or other materials but with reduced electrode wear and faster speed. The fine grain graphite electrodes have the ability to deliver quality surface finishing.

EDM Performance

The wholesale graphite electrode exporter provides this Graphite for the aerospace sectors as it works the best there. If there is any problem with the Graphite, then the issue is noticed immediately, unlike the copper, where the problem gets unnoticed and creates performance issues at the last moment.
