When it comes to EDM electrodes, having the best copper is essential for optimal performance, reports EDM Plus, a UK specialist in EDM machine sales, EDM consumables sales, EDM subcontracting and other related services. The company says that copper is an essential part of the process, as it provides the electrical current needed to create the spark that powers the machining process. The right copper for EDM electrodes will ensure consistent and successful machining.

Several types of copper are available for EDM electrodes, including oxygen-free high-conductivity (OHFC) copper, electro-refined (ER) copper and electrolytic tough pitch (ETP) copper.

For EDM electrodes, OHFC is the preferred choice because it offers excellent electrical conductivity, low resistivity and good thermal stability. It also has higher resistance to corrosion than other types of copper and is suitable for use in harsh environments.

When selecting EDM electrodes, EDM Plus says machine shops should look for those made with a high-grade OHFC copper alloy. This type of alloy offers enhanced wear resistance and is suitable for use in a wide variety of applications. Additionally, it has a relatively low coefficient of friction and can withstand higher temperatures for longer periods of time than other types of copper.

For added protection against wear and tear, consider using EDM electrodes made from an alloy containing additional elements like chromium or molybdenum. These alloys are more resistant to corrosion and are more suitable for use in corrosive environments. They also tend to offer improved properties when exposed to high temperatures or pressure.

Finally, keep in mind that the cost of EDM electrodes varies depending on the type of copper used. OHFC is generally more expensive than other types of copper, but its superior performance makes it worth the investment.
