ZAMAK 4
​​​​​​​
Zamak 4 was developed for the Asian markets to reduce the effects of die soldering while maintaining the ductility of zamak 3. This was achieved by using half the amount of copper from the zamak 5 composition

When compared to Zamak 3, the mold sticking problem is improved and the flexibility remains unchanged. It is commonly used to produce clothing accessory such as zipper pulls and zipper sliders.
