The teeth of a metal zipper are made of copper, white copper or aluminum. Metal zipper manufacturers are mostly used in high-grade products. The price is more expensive than resin zipper and nylon zipper.Metal zipper products are strong and are often used in jeans, coats and backpacks.
Avoid contact with wet environments when using: metal zippers can blacken some of the teeth caused by metal oxidation and dyeing. Avoid contact with rubber bands: because rubber bands themselves contain sulfides, metal chain teeth are vulcanized (blackened) when metal zippers are tied with rubber bands. Wash and dry in time after washing: because the dye or residual chemical in the fabric redox reaction with the metal part, may cause the metal part to change color. The above is the metal zipper maintenance and matters needing attention.
