Abstract
A method of forming an electrode for a spark plug is provided. The method includes machining locating holes within a blank material, inserting a rod of a different material into the locating holes and brazing the rod to the blank. An electrode receiving aperture is machined into the blank. The step of machining the aperture exposes a surface of the rod to form a contact portion of the electrode.
