Nickel, Aluminium, and Given Their Durability.

A metal zipper consists of two rows of protruding teeth made of metal. The metal teeth may be made of Brass, Aluminium or Nickel, and they are designed to interlock like clasped hands, linking the rows, thus creating a “Continuous Clothing Closure” For this to be possible, the metal zipper is usually fitted with a slider, often made of metal.
