No you need more copper
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.

long enough
Recycle and reuse aluminum
