Yes, but carbon has a relatively low reactivity.

Gold is an excellent conductor of electricity, but it is expensive. That's
why you see gold-plated connectors on audio plugs, as well as on PC cards
(and the slots they go into). And I think many of the runways in PC boards
are actually made of a micro thin layer of gold.

Though gold is a better conductor of electricity, I don't know if that means
electrical noise from external sources is reduced. Regular headphones sound
the same to me.

So, as copper is the next best thing, it is more widely used.
