Abstract
An electrode core material that may be used in electrodes of spark plugs and other ignition devices to provide increased thermal conductivity to the electrodes. The electrode core material is a precipitate-strengthened copper alloy and includes precipitates dispersed within a copper (Cu) matrix such that the electrode core material has a multi-phase microstructure. In several exemplary embodiments, the precipitates include: particles of iron (Fe) and phosphorous, particles of beryllium, or particles of nickel and silicon.
