Why does copper make a good metal to use in electrical wiring?

Copper, like all metals, is a conducter of electricity. Copper is particularly effective because of the way its electrons are arranged allows for more free movement of electrons which allows for more efficient conductivity. Copper is also very flexible which is ideal for wiring. This means thinner wires can be used which means it is cheaper than similar metals like Aluminium. despite being flexible it is also a very durable metal which means it is resistant against necking and breaks. Copper is also very ductile so it can easily be stretched into a wire.
