The AURUNA® 5750 electrolyte can be used to deposit approx. 12-carat gold-silver coatings (50 wt.% gold / 50 wt.% silver). These gold-saving coatings are characterised by their silver-like (yellowish-white) colour and good tarnish resistance. They are the ideal choice for saving gold and are mainly used as an intermediate layer under high-carat top coats. A major advantage is the exceptionally good ductility of the coatings, which ensures high flexibility and resilience. The electrolyte is easy to handle, insensitive to metallic impurities and is suitable for rack and barrel products.

A version with a low gold content (LC for ‘low content’) is available for thin layers. We also offer a cyanide-free form of the initial concentrate and the replenisher solution.
