If so please take note that copper plating on iron/cast iron will require a special type of copper plating solution because the normal CuSO4 solution will not work, that is because Copper is more noble than Iron and it will form a flash coat of copper on iron/steel, but that coat is spongy and comes off real easy!

During copper plating of an iron key, copper metal is transferred from the copper plate to the iron key through the copper sulphate solution. During electroplating with copper, copper metal gets transferred from positive electrode to the negative electrode.
