Project Description

ZA-4 / Zamak 4

Zamak 4

Zamak 4 was developed for the Asian markets to reduce the effects of die soldering while maintaining the ductility of zamak 3

zamak 4ZA-4ZA-4 / Zamak 4Zamak 4 / ZA-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.

High strength-to-weight ratio and good ductility
Better in mold adhesion problems encountered with Zamak 3
Good performance on clothing accessories such as zipper sliders and zipper pulls
