Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.

How does electric get to your home from a dam?
Along wires. Copper wires underground or aluminium overhead.
Why copper is used insted of alluminium in wires?
Copper is always preferred in houses because it conducts electricity better and does not corrode on the surface as easily as aluminium. But for overhead electric wires, aluminium is preferred because it is much lighter and the pylons don't have to be so massive.
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
Are copper wires and not steel wires used in electric circuits although both copper and steel are electrical conductors?
Steel is not used as an electrical conductor because, although it is a conductor, it's not a very good conductor -as is copper and aluminium, for example. A steel-wire core is used, however, to reinforce aluminium conductors on transmission tower lines
Can I use standard electric power supply copper wires in making a solenoid?
No, you need DC.
Why do you use copper wires in electric wires?
Copper is an excellent conductor, ductile (can be drawn easily), and reasonably economical. For bare conductors, copper oxidises and the oxide coating prevents further corrosion. While it is heavier than aluminum, it is stronger. The alternative, aluminium, is cheaper than copper, but not as good a conductor. Aluminium is lighter, but weaker, and aluminium transmission lines require a steel-core for strength. Aluminium conductors suffer from 'cold flow', which means that aluminium conductors secured with screw terminals tend to work loose over time. Copper doesn't do this, so copper is preferred for residential/commercial electrical wiring systems.
How has copper been used?
Copper has been used lately in wires and cables like coaxial and electric wires.
What is the metal used for electric wire?
Copper and aluminum used for electric wires
Why are copper wires used as the connecting wires?
Copper is a metal and as such it can conduct electricity very well. Additionally, copper is a very good conductor off heat when compared to the more abundant metals such as aluminium.
What is metal usually used for?
Copper is frequently used for electrical wires. Aluminium is cheaper but breakable.
Which are the other metals which are used as wires and why?
The two most common metals in order of preference are copper and aluminium.
What is electric cars made off?
The car itself is basically made of the same material as a fuel-furning car, apart from the batteries. Mostly steel, some aluminium, lots of plastic, and some copper for wires.
