The higher copper content gives Zamak 5 an improved strength but is less ductile than Zamak 3. This reduction in ductility can influence formability during operations like bending, riveting, or crimping. Zamak 5 can also be more readily plated or finished than Zamak 3. It has high mechanical strength and can be used in applications where parts are subject to high-stress levels. It also has good resistance to corrosion.
Excellent machinability • Improved strength • Low ductility
