Electroplating

Electroplating

Electroplating makes use of precious metal compounds by reducing the metal ions and depositing metals from aqueous solutions ("electrolytes") of compounds ("salts") in a micrometer and sub micrometer range. Precious metals can be deposited on surfaces in the form of thin layers and serve various purposes: They offer resistance to oxidation and corrosion, mechanical protection due to hardness and optical attraction with luster.

Heraeus manufactures suitable compounds and their solutions as core products, which serve for the production of plating electrolytes. They are mainly found in the fields of jewelry and electronics.
