Q. Hello...

I am a new electroplater. Also I am a chemist. So I need some information about cyanide copper brighteners. What do I use (which chemicals) for more bright plating ? Please, don't say me: "choose what do you want". I LOOK FORWARD TO YOUR ANSWERS.

Sincerely...

A. Past history of brightening cyanide copper deposits includes the use of tartrates (Rochelle Salts) ⇦ on eBay or Amazon [affil link] as well as the additions of selenium and arsenic compounds. There are also a variety of proprietary materials available that use organic compounds or a combination of metallic and organic compounds

A. Hi, Alaattin. Safranek's "The Properties of Electrodeposited Metals and Alloys" ⇨
recognizes not only Rochelle Salts, but a proprietary selenium-based material which acts as a brightener when applied with periodic reverse current. It does not recognize any other brighteners for cyanide copper baths.
