First off, not all electrical wiring is copper. There's a fair bit of aluminium wiring being used too, as well as some other alloys.
"Pure" is a difficult word. You can have copper that is purer than what's used for electrical wiring. But outside a lab setting, copper wire is indeed pretty darn pure.

What is the aluminum wire equivalent to?
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
What are raw materials for making copper wires?
Copper. The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C11040). This copper is at least 99.90% pure.
What is the minimum size wire allowed for a parallel run?
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
Composition of copper wire in generators?
how much copper is in copper wire
Do ground wires have to be covered with wire insulation?
Not always, the electrical code is quite specific as to the type of installation where the ground wire needs to be insulated and in what type of installation the ground wire can use bare copper.
Is copper wire a mechanical mixture?
It should be a "pure" substance, but its really an alloy.
What can pure copper be used for?
Pure copper is used for electrical wiring. Pure copper conducts electricity better than impure copper.
What are the elements in a copper wire?
If the copper wire really is pure copper then the only element in the copper wire is copper (Cu).
Is copper wire pure copper?
Very few things are 100% You can find copper wire with 99.999% purity commercially. The purity of copper is expressed as 4N for 99.99% pure or 7N for 99.99999% pure. The numeral gives the number of nines after the decimal point when expressed as a decimal (e.g. 4N means 0.9999, or 99.99%). Much electrical wiring is not more than 99,9% copper. Very small amounts (some tens or a few hundred parts per million) of impurities have a rather large effect on the electrical conductivity of copper. Oxygen is intentionally alloyed into copper to scavenge sulphur and hydrogen which have various unwanted mechanical and electrical effects on the finished product.
Why does an electrical circuit have a copper wire?
If you mean a bare copper wire, that is the "ground" wire.
Is copper wire a pure substance heterogeneous mixture or homogeneous?
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
Is copper wire a pure substance mechanical mixture or a solution?
pure substance
What mineral are in electrical wire?
Copper!
What Type Of Copper Wire Conducts Electricity Best?
The more pure the better. Pure copper.
What is the predominant carrier of electrical charge in a copper wire?
Electrons are the predominant carriers of charge in copper wire.
Why is copper used for solar energy?
electrical wire
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
