Equivalent Materials
- ZA-27: strongest and hardest in the ZA series with excellent bearing properties and superior wear resistance
- ZA-8: balanced combination of strength, hardness, and elongation; suitable for hot chamber die casting with superior plating finish
- ZA-12: provides good castability and impressive mechanical properties, balanced between ZA-8 and ZA-27
Characteristics
Zamak 5 delivers superior mechanical properties compared to Zamak 3, driven by its higher copper content (0.7-1.1%). The alloy demonstrates excellent thermal conductivity, enhanced corrosion resistance from aluminum and copper, superior surface finish, strong dimensional stability under stress, and noteworthy electrical conductivity from its high zinc content.
Compared to equivalents: ZA-27 offers higher tensile strength and better dimensional stability but its high aluminum content limits hot-chamber die casting use; ZA-8 enables hot-chamber die casting and superior plating but has inferior mechanical properties; ZA-12 balances mechanical properties and castability between the two.
Uses
Applications span automotive parts, hardware components, toy manufacturing, and decorative items. The enhanced strength from copper content makes Zamak 5 ideal for applications requiring rigidity. Hot-chamber die casting enables production of complex shapes with high precision and excellent machinability.
