MIRALLOY® For the Clothing Industry

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

Since 1981, MIRALLOY® has been a good alternative for nickelfree coatings in the clothing industry. Today, our customers all over the world profit from more than 30 years of experience and the continuous further development of the product series.

With MIRALLOY®, electrolytes are used to deposit copper-tin(-zinc) coatings in rack and barrel plating. The colour of the coatings is white – similar to silver.

Plated garment accessories, such as zips and metal buttons, offer a very high level of resistance to everyday wear.

A further plating layer with gold, rhodium, palladium or other precious metals, as well as tarnish protection if required, can be added problem-free by choosing a suitable process and with the right pre-treatment.
