The metal zippers on the market are mostly made of aluminum alloy, brass, copper, zinc alloy and other materials. Because the color of the teeth on the metal zipper is electroplated, if not properly stored, the teeth will become black and pollute the material. For copper alloy teeth are prone to oxidation, so when stored to ensure a certain amount of ventilation, do not seal storage, do not keep in a humid environment, when necessary to use anti-wet paper or dehumidifier.
