The center electrode and the side electrode of the spark plug are generally made of different materials. The material of the central electrode has undergone several evolutions of iron, nickel, nickel-based alloys, nickel-copper composites, and precious metals. The side electrode is generally the same material as the body of the spark plug, but in order to reduce the effects of electrocorrosion and chemical corrosion, elements such as manganese and silicon are added to the nickel base to improve corrosion resistance. As the performance of the engine increases and the load increases, the side electrodes are also using more advanced materials, but in order to reduce the cost, only a small amount of precious metal is welded to the head of the side electrode.
