AURUNA® 8000 Gold-Iron High-Speed Electrolyte

Sustainable High-Speed Hard Gold Plating

AURUNA^® 8000 is an innovative gold-iron high-speed electrolyte that combines high process speed with excellent coating quality and is completely nickel- and cobalt-free. Sustainable hard gold plating in high-speed systems and for brush applications is therefore no longer a contradiction in terms.

The electrolytic process enables low-porosity, extremely wear-resistant hard gold coatings with a fineness of around 99.7% and a hardness of approximately 130 HV. The coatings thus comply with ASTM B-488-01: Type I, Code C and are also suitable for demanding technical applications.

AURUNA^® 8000 is a future-proof, sustainable alternative that does not require any adaptation of existing process landscapes. The possible use of AURUNA^® Inhibitor 2, which enables gold savings of up to 15% in selective applications by minimizing the run-off zone, also makes AURUNA^® 8000 economically attractive, especially in times of high gold prices.
