Rhodium electrolytes from METAKEM supply brilliant white surfaces on silver, gold and white gold. Apart from brightness and excellent white colour, the corrosion resistance and hardness of this precious metal is commonly appraised. By rhodium electroplating of silver achieves a lifelong tarnish protection and preserves its natural brightness at the same time. For the production of premium jewellery and also reed contacts, the use of high-quality rhodium electroplating baths is essential.
