What is often used in electronic wiring?? copper, iron, silver or aluminum?

Answer 1

Copper is the most common, but gold and silver are better conductors. Due to their higher cost they are only used on high end equipment.

Answer 2

Copper is used more than anything, consuming about 83% of all electrical wiring needs in the U.S.
Iron has never been used and will never be used for any electrical wiring
It is too heavy, not malleable enough and is VERY non-ductile ( a metal's ability to be drawn into wires) It is also too brittle and it rusts too easily
Silver is too expensive for household wiring but it is a much better conductor than copper. It is used in most mid-range electronics but it is not suitable for
microchips. This is where gold comes into play
Aluminum, while cheap and plentiful, it is a lesser electrical conductor and it
has some of the same problems as iron; it is too brittle to be drawn into thin wire strands and breaks easily when it is so thin.

Answer 3

Copper... but some aluminum was used to wire houses for a while. Aluminum wiring is considered sub-standard, but I'm not sure why. Does anyone else know?

Answer 4

Copper is most common. I think aluminum is too easy to melt.

Answer 5

copper
