Choose the Right Gold Plating Bath Alkaline, Neutral, Acid

Gold plating baths can be broken down into three basic types: alkaline, neutral and acid. Let's take a closer look at each type: gold plated part nist. Alkaline An alkaline bath is a non cyanide solution with a pH level ranging from 9.0 to 13.0. Sodium gold sulfite serves as the source of the gold metal ions that are deposited.
