Copper is generally known to be among the top conductors of electricity, and its high conductivity is a primary reason why it's used extensively in electrical systems—such as in pieces such as copper cable lugs. With a good electrical conductivity rating of 97% IACS (International Annealed Copper Standard), copper facilitates electric current flow with minimal resistance.
