Direct plating with excellent adhesion is possible on stainless steel and nickel.
AURUNA 311 allows for direct, highly adhesive gold plating on stainless steel for functional parts. Due to the very high activation effect of the plating bath, it is suitable for difficult-to-plate materials that are hard to activate, particularly chromium-nickel-molybdenum steel or nickel alloys. It has few pinholes, high ductility, and excellent corrosion resistance. It is suitable for both strike plating and thick plating.
