Performance features and classification of Nickel Free Zipper
The tape's color matches the garment's, as does the slider, so that, except the slider, the zipper is "invisible". This kind of a zipper is common in skirts and dresses. Nickel Free Zippers are usually coil zippers. They are also seeing increased use by the military and emergency services due to the fact that the appearance of a button down shirt can be maintained, while having a quick and easy system.
metal zippers are the classic zipper type, found mostly in jeans today. The teeth are not a coil, but are individual pieces of metal moulded into shape and set on the zipper tape at regular intervals. Metal zippers are made in brass, aluminium and nickel, according to the metal used for teeth making. All these zippers are basically made from flat wire. A special type of metal zipper is made from pre-formed wire, usually brass but sometimes other metals too. Only a few companies in the world have the technology.
