Electrodes for Spark Plug Applications
Increasingly high quality materials and components are being used in order to meet the growing requirements for combustion engines with respect to fuel efficiency and emissions.
About Electrodes for Spark Plugs
High-quality materials based on precious metals are increasingly utilized for spark plug electrodes. These materials offer thermal stability and long service life due to their resistance to wear and oxidation. We customize the mechanical properties to meet your specific requirements for optimal processing and workability.
Greater efficiency in fuel combustion and reduced CO2 emissions lead to compliance with future environmental standards. Our electrode materials for center and ground electrodes in spark plug applications are manufactured from high-quality alloys of the platinum group metals, enabling spark plugs to outlast conventional variants with non-precious electrodes by a significantly greater margin.
