Metal Electrode

Mar 09, 2017

In the early days of spark, the metal electrode was the only electrode. Now, metal electrodes only account for only 10% of EDM applications (except for processing holes). The main advantages of metal electrode materials are their electrical conductivity and mechanical integrity. Mechanical integrity is important, especially for acute and poor flushing conditions (DC arc). The main drawback of metal electrodes is manufacturing difficulties and cutting speed is slow. The following are more information on commonly used metal electrode materials
