The most suitable plating solution for cost reduction.
AURUNA 5750 is a plating solution of approximately 12 carats of gold-silver alloy (50% gold / 50% silver). The resulting film exhibits a pale yellow color. It demonstrates high corrosion resistance and excellent ductility, resulting in high durability. Even when finishing with high-purity gold plating, it is possible to reduce gold usage by employing AURUNA 5750 as an intermediate layer. The stability of the bath is high, and it is resistant to the contamination of inorganic impurities. It is compatible with both rack plating and barrel plating.
