EFO… a new age in performance, quality and cost. Stainless Steel Body: Lower cost compared to Platinum; stronger and good conductivity. Crimped or Blazed Platinum Tip: Excellent conductivity, withstands 1769°C compared to Gold of 1000°C. Typical spark gap between EFO and Gold-wire for sparking is 0.030" (0.076mm) with 3000 volts applied to form a gold ball at the top of the wire.
