Nails are indispensable in many things, from small handicrafts and do-it-yourself projects to large construction sites. Nails have a variety of shapes and sizes. Some of the aluminum alloys used for YKK® fasteners are also used for nails.
Aluminum has the image of being lighter and softer than iron or stainless steel, but YKK® aluminum zippers use a 5,000 series aluminum alloy combined with magnesium to improve the material properties such as strength.
