It should be a "pure" substance, but its really an alloy.
Copper wire is a pure substance, as it is made entirely of copper atoms.

Copper wire is matter that is comprised of only one type of substance, which is copper. This substance is made up of copper atoms arranged in a specific pattern that gives the wire its unique properties.
copper is an ELEMENT therefore it is not a heterogeneous OR homogeneous mixture.

Copper wire is homogeneous.
copper is a 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.
it is substance
Copper metal is an element and thus a pure substance.
Copper wire is matter that is comprised of only one element: copper. It is a pure substance because it is made up of only one type of atom.
Yes, it is a homogenous mixture.
