From high quality alloys of the platinum group metals

High quality materials based on precious metals are being used more and more for electrodes in order to meet the requirements of today’s combustion engines (low fuel consumption, lower emission values).
Our electrode materials for applications in the center and ground electrodes of spark plugs are manufactured from high value materials of the platinum group metals. This means that the spark plugs achieve a service life many times greater than that of conventional spark plugs of non-precious metal. Heraeus is a manufacturer of materials for spark plug electrodes which are offered in the form of continuous and cut wires, rivets, balls, disks and crosses. Moreover, you receive customer-specific shaped parts and composite parts. Let us advise you before we give you a quotation.
Besides longer service life due to the wear and oxidation resistance of electrodes, our electrode materials based on precious metals offer further advantages: higher efficiency due to optimal fuel combustion and decreased CO2 emission. This means that future, more stringent environmental requirements can be met.
