Electrolyte for fine gold hollow jewellery
AURUNA® 556 EF-24 is particularly suitable for electroforming. The electrolyte produces hard, semi-bright, thick gold layers. It is mainly used to produce high quality hollow jewellery with layers between 150 and 200 micrometer. Mandrels may be either made of wax or metal. The excellent hardness up to 200 HV and more than 99.9 percent fineness ensure customer satisfaction, because the hollow jewellery offers outstanding stability in use. It can be polished easily, has good surface quality and convinces with its solder properties.
AURUNA® 556 EF-24 is also ideal when thick fine gold layers are deposited on (non-) precious metals. Creative combinations allow completely new designs.
