MIRALLOY® For Costume Jewellery

Copper-tin-(zinc) electrolytes as nickel-free alternatives

MIRALLOY® has been offering alternative nickel-free plating for fashion jewellery since 1981. With MIRALLOY®, electrolytes are used to deposit copper-tin or copper-tin(-zinc) coatings in rack and barrel plating. Depending on the electrolyte used, white or yellow layers can be deposited.

MIRALLOY® coatings stand out due to their excellent distribution of metal and, depending on the bath type, high tarnish resistance, levelling, abrasion resistance and exceptional corrosion resistance. A further plating layer with gold, rhodium, palladium or other precious metals, as well as tarnish protection if required, can be added with the right pre-treatment to create optimal corrosion protection.
