Materials and their applications in the electrical industry

The best electrical conductor known is silver but this is far too expensive and rare to provide all the conductor material required by the electrical industry. Next in order of conductivity come copper and aluminium and these are the most important current-carrying materials used in cable and line manufacture. Other materials used are cadmium copper, phosphor bronze and for some high-voltage low power links, galvanized steel.
