Who Does/Offers White Bronze Plating?


I have a customer who is interested in our doing a barrel copper-tin-zinc tri-alloy deposit for electronics applications. The alloy goes by many names including "white bronze", "Albaloy", or "Sucoplate." I've also heard it referred to as using the "Tagusha" bath from Germany, however, I suspect that there are many available commercial applications (especially in Europe).

I'm looking to hear from people who've operated such baths. Is it difficult? What anode materials used? Is it readily solderable and how does it age? Who are potential suppliers for this chemistry? Any information in this regard would be appreciated and is most helpful.

There was a full page ad in the January 2001 Metal Finishing mag for a product called Miralloy (Cu/Sn/Zn alloy)by Degussa Galvanotechnik (your tagusha?) giving the North American distributor as Uyemura International Corp.
