AURUNA 3408// Cyanide-free gold electrolyte
Cyanide-free gold-copper electrolyte with exceptionally high purity
AURUNA 3408 is a cyanide-free gold-copper electrolyte whose gold layers are characterized by an exceptionally high fine gold content of approximately 99.7%. Despite this high purity, the layers exhibit impressive mechanical stability, with a hardness of up to 180 HV according to Vickers. Thanks to the low internal stresses, layer thicknesses of up to 10 micrometers are possible without cracking or delamination. AURUNA 3408 does not contain any questionable grain refiners such as arsenic, thallium, lead, cadmium, cobalt, or tellurium. This means that the electrolyte is not only non-toxic, but can also be used worldwide without restrictions – a clear advantage for environmentally conscious production processes.
