Spark Erosion Materials

Spark Erosion, also known as Electrical Discharge Machining (EDM), is a manufacturing process where a desired shape is obtained from a workpiece by using electrical discharges or sparks. This method is often used when the material is extremely hard or when the design is complex and requires a high degree of precision.

The term “Spark Erosion Materials” refers to the materials used in the EDM process, particularly the electrodes. In the EDM process, the electrode and the workpiece do not make physical contact. Instead, an electrical discharge or “spark” jumps the gap between the electrode and the workpiece, eroding the workpiece material into the desired shape.

The electrode can be made of a variety of materials, but graphite and copper are the most commonly used. Graphite, in particular, has become popular due to its ability to withstand high temperatures, resistance to deformation under heat stress, and its slower erosion rate, leading to less frequent electrode replacement.

Erodex, with its 50 years of expertise, is a leading distributor of spark erosion materials, including graphite and other EDM consumables. They understand the critical role these materials play in the EDM process, providing tailored solutions that help their clients maintain a competitive edge. Not only do they supply premium spark erosion materials, but Erodex also offers a range of comprehensive services encompassing consultation, design, and machining, solidifying their role as a trusted partner in the industry. By understanding and meeting customer-specific needs, they ensure optimal performance and cost-efficiency in the EDM process. To keep up to date follow us on our Erodex Facebook page.
