• Big difference was found between wire EDM characteristics of SiC and cold tool steel SKD11.
• Fracture generation may contribute to the material removal process of EDM of SiC.
• A new EDM cutting method utilizing foil electrode was proposed and investigated.
• Short pulse duration was more suitable for EDM SiC.
• Minimum kerf width of around 100 μm was obtained utilizing the foil EDM method.
