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.
Composition of copper wire in generators?
how much copper is in copper wire
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.
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 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.
Is copper wire a pure substance mechanical mixture or a solution?
Copper wire is a pure substance, as it is made entirely of copper atoms.
What is the chemical name of copper wire?
Copper. The wire is made of elemntal copper not a chemical compound. (Note the copper used may sometimes be alloyed with another metal or occasionally be a solid solution of small amounts of oxide in the pure metal. This improves the durability and handling characteristics of the wire.)
Is copper wire a mechanical mixture?
It should be a "pure" substance, but its really an alloy.
Is copper wire a pure substance heterogeneous mixture or homogeneous?
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.
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?
No. Copper used in wiring would not qualify as laboratory-grade (pure). It would be far too expensive to manufacture and would not improve the conductivity enough to make a difference. Some copper wire is even plated. Laboratory-grade (pure) copper is a single substance, the element copper.
What are the advantages of using copper coated aluminum wire in electrical applications?
Copper coated aluminum wire offers the advantage of being lighter and more cost-effective than pure copper wire, while still providing good conductivity. This makes it a practical choice for electrical applications where weight and cost are important factors.
Is a copper wire a mechanical mixture a solution or a pure substance?
It should be a "pure" substance, but its really an alloy.
What mineral are in electrical wire?
Copper!
What is the difference between copper bare and copper millberry wire?
Copper bare wire refers to uninsulated copper wire that has not been processed, while copper millberry wire is clean, untinned, uncoated, and unalloyed copper wire that is at least 99.9% pure. Millberry wire is typically used for high-quality applications like electrical wiring due to its purity and consistency, while bare copper wire is more commonly used for grounding applications.
What can pure copper be used for?
Pure copper can be used in electrical wiring and plumbing due to its excellent conductivity and corrosion resistance. It is also used in the production of various industrial components, such as heat exchangers and motors, as well as in crafting artistic items and jewelry.
