Aurusin 5N is a gold electrolyte intended for bath plating, which deposits a uniform, shiny 5N color layer. 5N can be described as a reddish yellow with warm brown undertones. Aurusin 5N is intended for decorative use. It is, therefore, designed for flash plating, allowing for a deposition thickness of up to 0.2 micron. This yellow gold plating solution is nickel-, lead-, and cadmium-free, despite being a traditional cyanide-based alkaline bath.
