    Excellent Layer Thickness Distribution

    AURUNA® 526 is a weakly acidic gold-cobalt electrolyte with very good throwing power and layer thickness distribution, especially on hollow parts.

    This makes the electrolyte perfect for use of bulk material in barrel and vibration coating facilities. The interiors of cases or sockets often need to be gold-plated. The excellent throwing power therefore very positively influences the layer thickness distribution between the interior and exterior surfaces. This optimum distribution means gold can be saved.

    The deposited layers have very good wear resistance, low contact resistance and impressive corrosion resistance.
