High Performance Graphite

EDM-4 graphite, developed for mold shops that need high performance in critical applications, has been introduced by Poco Graphite (Decatur, TX). The graphite—with a smaller grain size and higher strength than the company’s EDM-3—has less wear and produces better surface finishes.

EDM-4 graphite, developed for mold shops that need high performance in critical applications, has been introduced by Poco Graphite (Decatur, TX). The graphite—with a smaller grain size and higher strength than the company’s EDM-3—has less wear and produces better surface finishes. EDM-4 is ideal for applications with extreme tolerances in medical, automotive, semiconductor and aerospace industries. In some cases, end users report 10 to 15 percent improvement in wear on finishing electrodes and better surface finishes.
