History:
Electroplated Tin-Zinc alloy is certainly not a new finish however it may not be familiar to a great many Material Engineers , Design Engineers, and Corrosion Specialists. Electroplated Tin-Zinc Alloy has been around since the 1940’s. These first electroplating baths utilized a sodium hydroxide / cyanide electrolyte, were very difficult to operate, and required a significant amount of control and service. The popularity of tin-zinc declined in the early 1970’s in part due to the unpopularity of the use of cyanide.

In the mid 1980’s electroplated Tin-Zinc re-emerged . Research and Development by Plating Technology led to a new plating system which eliminated the use of cyanide and replaced it with environmentally friendly alternatives. Throughout the years, the system has been refined and is now the standard for applying quality tin-zinc alloy coatings.

The popularity of electroplated Tin-Zinc alloy continues to grow as people discover its engineering properties and the superior corrosion resistance it provides in numerous environments.  With the increasing global push to “go green”, Tin-Zinc may ultimately offer the best alternative as nickel, cobalt, and chromium continue to be scrutinized by the European Union (EU) and “blacklisted.”
