Wires are made of many metals (and even non-metals). Field telephone wires for military use are steel. The Electric Company uses more aluminum than copper. Silver is the best conductor. Gold is used to wire integrated circuits because it does not corrode.
Aluminum wire can be used with caution in treating the connections so they don't corrode. Many metals will conduct electricity.
What gets used is based upon economics as well as conductivity or the ability to carry a certain current load for a certain size wire.
Gold is the best conductor but is expensive. Silver is next in line. Copper and aluminum are the most cost effective and allow ample current to pass for a given size of wire.
brass is a good replacement its soft like copper
For electrical applications aluminum is often substituted in power transmission. Gold and silver are used for contacts and wire.
For pipework and vessels, any ductile material is used.
No. Other things being equal, a long wire has more resistance than a short wire.
no
The Air is many molecules scattered all around and copper wire is molecules in a line and very condensed where air is not. Therefore copper wire is a better conducter
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
There are several metals able to be stretched into wire. In electrical wiring, copper or copper coated aluminium is commonly used. Steel is also able to be stretched into wire.
Yes
Copper is more stronger against other metals.
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).

how much copper is in copper wire
No. Copper wire is a solid
No.. Copper wire isn't
Copper wire sent for recycling is remelted and rerefined. It becomes a new copper product one of which might be new copper wire.
copper wire that is coated with tin
If you mean a bare copper wire, that is the "ground" wire.
