POCO?s premier offering in the Ultrafine classification. This highly isotropic grade combines extraordinary strength with moderate hardness, yielding superior electrode fabrication characteristics. The consistency of EDM-4 also makes it an excellent choice for highly detailed wire cut electrodes. EDM-4 is reasonably priced, making it the cost performance leader for most applications requiring a high quality Ultrafine graphite. EDM-4 is the ideal choice for jobs requiring excellent machinability, low electrode wear & smooth surface finishes.
