AURUNA® 5300 Gold Iron Electrolyte

Nickel-free, fast-depositing weakly acidic electrolyte

AURUNA® 5300 is a hard gold electrolyte free of nickel and cobalt with high plating speed for decorative and technical applications. The weakly acidic electrolyte for depositing yellow, bright hard gold coatings exhibits good corrosion and abrasion resistance. Its contact resistance is low and long-term stable. Metallic contaminants can be easily precipitated.

The hard gold electrolyte can be used for rack and barrel operation. It is especially suitable for jewellery since the coatings are free of nickel and cobalt.
