MIRALLOY® Copper-Tin-(Zinc-) Electrolytes

Barrel and rack plating electrolyte for functional applications 

MIRALLOY® has been offering nickel-free plating for the connector, clothing and fashion jewellery industries for more than 30 years. You can benefit from our experience and the ongoing development of our product range. The trademark MIRALLOY® comes from the English words “mirror“ and “alloy“. It refers to the Bronze Age, when copper and tin were used to make mirrored alloys.

MIRALLOY® denotes electroplating processes for the deposition of alloy coatings of copper and tin or of copper, tin and zinc. Depending on the electrolyte used, white or yellow layers can be deposited. You can choose electrolytes for rack and barrel plating from the wide range of MIRALLOY® processes available.
