Copper
Copper is a great electrical conductor with low resistance.
Almost all spark plugs use a copper cored center electrode to conduct the electricity, jump the gap, and promote heat dissipation. However, due to its soft nature and low melting point, using copper as an outer electrode material would result in a plug that lasted only minutes.
“Copper spark plugs” is a term mistakenly used for a standard or traditional spark plug. A standard spark plug traditionally uses a nickel-alloy outer material fused to the copper core. Some plugs include a coating or pad of precious metals such as iridium or platinum to extend plug life. But as a general rule of thumb, all spark plugs utilize a copper core.
