The prices for rhodium and palladium have exploded over the last few years along with production costs. In order to be able to continue to serve the market, a rethink in surface plating is required. Alloys represent a way out for both decorative and technical applications, with almost no compromise in quality and appearance. On the contrary - through innovative processes, we have succeeded in improving properties such as abrasion resistance or adapting colour composition as required.

AURUNA® 215 Pale is a colour gold alloy electrolyte for decorative applications, preferably for parts coming into contact with the skin such as jewelry and watches. The essential advantage of the coatings is their freedom from nickel and cobalt, excluding skin allergies caused by these metals.
The process has already been proven for many years. By changing the parameters, we can now also achieve a pale yellow color (1N). It is easy to operate and suitable for rack and barrel.

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.
