Spark plug electrodes operate under extreme thermal, electrical, and chemical conditions throughout millions of combustion cycles.

Platinum and specialty precious metal alloys provide exceptional resistance to erosion, oxidation, and high-temperature degradation, allowing ignition systems to maintain consistent spark gaps and reliable engine performance over extended service intervals.

Sigmund Cohn Corp. manufactures precision platinum electrode materials that help automotive manufacturers improve ignition reliability, fuel efficiency, emissions performance, and component life.
