Metal conductors - General presentation

Copper and aluminum play a key role in the development of electrical conductors. They are also the basis for alloys that enable the compromises required by certain applications to be achieved, and are also found in bimetallics and coated metals. In perpetual competition and after many struggles and battles, the game is practically up, each metal having reserved for itself the sectors specific to its competence, modulated somewhat by the economic factor. But will their monopoly last in the face of newly-discovered superconductors and composites with emerging applications?
