Iridium as an electrode material is almost unaffected by spark erosion.
Iridium makes it possible to produce very thin middle electrodes with a diameter of only 0.6 mm.
At the thin middle electrodes, more flammable fuel mixture reaches the ignition spark. This ensures reliable ignition and better spread of the flame front.
