AURUNA® 504 Rose Gold Electrolyte

Gold-saving gold-copper coatings for decorative and technical applications

AURUNA® 504 is an alkaline electrolyte for the deposition of red gold-copper alloy coatings with a caratage of 16 – 18 carat. The process, which is based on gold(I) cyanide and free cyanide, is suitable for both decorative and technical applications. It is characterized by high electrolyte stability and easy operation.

The layers are ultra-bright, highly ductile, hard and abrasion resistant. As low-carat gold-saving coatings, they also exhibit very good corrosion and tarnish resistance.
