Why is iron galvanised with zinc? Can it be galvanised with copper? If not,why?

(N/A) Iron is galvanised with zinc to protect it from rusting. This is because zinc is more reactive (more electropositive) than iron,so it forms a protective layer that prevents corrosion. Copper is less reactive (less electropositive) than iron. Therefore,iron cannot be galvanised with copper because copper would actually accelerate the corrosion of iron if the coating were damaged.
