Metal zippers are the oldest type of zipper in zipper history. Metal zippers are mainly made of brass, nickel and aluminium. and given their durability, they are mostly used in jeans, workwear, heavy luggage and heavy-duty garments that must withstand high strength and tough washing. 

Brass and aluminum are the two materials that are most frequently utilized in metal zippers. There are several parallels between brass and aluminum, such as the fact that both oxidize with time. Depending on how they are wound or coiled, they also suffer similar performance losses. There is ongoing discussion concerning which metal performs best, in part because of these considerations.

Aluminum is far less expensive to produce than brass or copper when creating zippers, which has benefits for business. The price of our 4UZIP aluminum alloy zipper is 40% less than the price of the brass zipper. particularly when both metal zippers can be utilized for various purposes. In some situations where both metal zippers function equally well, switching from brass to aluminum zippers can be the only sensible course of action. What's more, it can significantly increase margins for our manufacturing clients. The feedback from our present clientele indicates that zippers made of aluminum alloy are frequently utilized on bags and bag packs. Aluminum alloy zippers are so strong and long-lasting that they can withstand the stress created when a bag is closed.

On the other hand, copper and brass cost a lot more than aluminum. Our manufacturers were once again made more uneasy by the copper price fluctuations. However, there are benefits as well, as copper is more durable than aluminum. There are some uses for copper/brass zippers that aluminum alloy zippers cannot take the place of, including denim clothing and footwear. The point is that there are still a lot of cases where an aluminum zipper would be a much more cost-effective alternative to a copper or brass zipper.
