Component Specifications

Definition
The electrode body or shank is the central structural component of an EFO (Electrical Flame-Off) electrode or wand, designed to conduct high-voltage electrical current from the power source to the electrode tip. It maintains precise dimensional stability and electrical conductivity while withstanding thermal and mechanical stresses during spark erosion processes.
Working Principle
Functions as an electrical conductor that transmits pulsed DC or AC current to create controlled electrical discharges (sparks) between the electrode tip and workpiece, enabling precise material removal, welding, or surface modification through thermal erosion.
Materials
High-purity copper (C10100/C11000), tungsten-copper alloys (WCu), silver-tungsten (AgW), or graphite composites with conductivity >90% IACS, thermal conductivity >200 W/m·K, and hardness >80 HRB.
Technical Parameters
  • Length 50-300 mm
  • Diameter 3-20 mm
  • Conductivity >90% IACS
  • Surface Finish Ra 0.8-1.6 μm
  • Electrical Resistance <0.1 Ω/m
  • Straightness Tolerance ≤0.02 mm/100 mm
Standards
ISO 12176-2, DIN 8580
