Miralloy – An electroplating alloy combination of tin, copper and zinc, is an excellent alternative to nickel for zippers, buttons and clasps. Approximately 20% of the world’s population has a skin reaction to nickel metal. The longer this metal is in contact with skin, the more likely it is to cause a burn. Miralloy is a high-quality, cost-effective finish that is inert and long-lasting. It’s available in white or yellow versions (the latter is an under-plate for gold) and is used worldwide for zippers, buttons, clasps and decorative metal on all types of apparel. White Miralloy is often referred to as “white bronze.” It doesn’t tarnish and withstands normal clothes washing and drying. Miralloy is also available in a lead-free white version, and this is the variation most often used in North America. Eballoy – is a tin-cobalt alloy “colorizer” that can be used over Miralloy or copper plated parts. Eballoy is available in black or white versions. Miralloy is a trademarked product from Umicore-GT; Eballoy is from CL Technologies.
