Electroplating WITH Brass (Not ON Brass)  

++++

Brass is an alloy of zinc and copper. How then is it possible to electro plate with brass? Why doesn't the brass dissociate in the bath into copper and zinc.

It does dissociate into copper and zinc ions. And then the copper and zinc ions deposit on the item to be plated and are reduced to copper and zinc metal.

That is not to say it's easy to brass plate--there are other difficulties not mentioned here; but it is fairly common.
