Nickel Coated Copper Core. ZEX™ has developed "Igniter Core Technology", which puts a copper core inside the nickel ground strap. Copper conducts electricity and heat over 4X better than nickel alone, with this unique hybrid design, you get copper's incredible electrical and thermal properties, for optimum spark and heat transfer, yet still retain a nickel shell for long life and durability. It is truly the best of both worlds.
