To make spark plugs, manufacturers first extrude or cold-form steel to the proper hollow shape (1). At this point, the steel forms ore called “blanks.” Next, these blanks undergo further forming operations such as machining and knurling (2), and then the side electrode—with only a partial bend—is attached (3).
What material is a spark plug made of?
While almost all spark plugs feature a copper core, many people refer to the common spark plug as a “copper” spark plug. A standard spark plug typically features a nickel-alloy outer material fused to the copper-core electrodes. Copper spark plugs run cooler and provide more power in performance driving situations.
