POCO's EDM-4 is our 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 material for wire cutting intricate electrodes. EDM-4 is reasonably priced, making it the cost performance leader for most applications requiring a high quality Ultrafine graphite.
