No. The primary reason copper is used in electrical applications is that it has a low electrical resistance. Because of the low electrical resistance, for a given current, wire length, and wire gauge, less power will be dissipated in a copper wire than in an aluminum wire. The heat spreading ability of copper is a tertiary concern.
