MIRALLOY® Nickel free

No nickel allergies by copper-tin-(zinc) electrolytes 

Nickel is the world’s main contact allergen. In Europe, around 15 to 20 percent of women and around five percent of men are sensitive to nickel - in women under 30, this figure rises to around 40 percent. Once someone has developed a sensitivity, constant or repeated contact with the allergen causes the skin or mucus membrane to react with inflammation (e.g. skin rash). The use of nickel is restricted by Annex XVII to Entry 27 of REACH. The definition of ‘prolonged skin contact’ (ECHA Q&A No 935) has resulted in many consumer objects that previously were not affected by the nickel limit now being covered by the 0.5µg/cm²/week maximum.

In contrast to nickel, MIRALLOY® platings do not cause any allergic reactions in accordance with current scientific knowledge, meaning they provide a great alternative. In combination with nickel-free substrate materials and other nickel-free processes, the MIRALLOY® process facilitates the manufacture of skin-friendly products. Its skin tolerance has even been proven in trials with sensitive test subjects. MIRALLOY® has been successfully used as a nickel-free coating on objects all around the world.
