Abstract : The patent concerns a principally phosphoric acid electropolishing bath for copper beryllium wire. It is characterized by additions of small amounts of copper sulfate and ammonium sulfate (or of copper ammonium sulfate), and sodium molybdate, and a fluoboric additive. This bath is for use in preparing the surface of copper beryllium wire for subsequent copper coating and/or plating with magnetic recording material in the making of magnetic memory system wire.
