Neutral, cadmium-free electrolyte for red layers
AURUNA® 503 is a neutral, cadmium-free gold-copper electrolyte for the deposition of bright red surfaces. It works without free cyanide.
AURUNA® 503 is especially suited to decorative but also technical applications, such as sliprings. Special features of this electrolyte are its long lifetime and fast deposition speed. For low-carat gold-saving layers, it also offers good resistance to corrosion and abrasion.
The gold-copper electrolyte can be used for rack and barrel plating and can achieve layers up to 5 μm in thickness.
