Abstract
A compound electrode, in particular an electrode for a spark plug, has a core composed of a first electrically conductive material, and a casing deformed to surround the core and composed of a second electrically conductive material. The casing is formed in a single extrusion molding step that also shapes the core and simultaneously forms the cross-sectional profile of the electrode.
