Graphite Grade for Precision Applications

EDM-3 is the graphite grade of choice for many precision moldmaking applications.

EDM-3 is the graphite grade of choice for many precision moldmaking applications. As with all POCO (Decatur, TX) grades, EDM-3 is produced to be consistent from block to block and year to year with uniform microstructure that is tightly controlled to yield predicable results from job to job. EDM-3 is ideal for fabricating detailed electrodes for production of high quality cavities for automotive applications such as speaker grills, H clips, connectors and support ribs. EDM-3 exhibits good wear in exotic metals, high strength performance in deep ribs less than .030” thick, and overall produces cavities with sharp corners and smooth surface finishes less than 30 Ra with ease
