Equivalent Materials

  • ZA-8: provides increased strength and hardness while maintaining excellent casting ability
  • ZA-12: offers superior strength and hardness with reduced castability
  • ZA-27: similar properties to ZA-12 with excellent wear resistance and lower densities

Characteristics

Zamak 3 exhibits strong mechanical properties with a tensile strength of 415.2 MPa and yield strength of 27.0 MPa. The alloy demonstrates superior plating properties, making it ideal for applications requiring aesthetic finishes. Key properties include excellent corrosion resistance, heat resistance, electrical conductivity, surface hardness, and impact resistance.

The material maintains superior long-term dimensional stability and excellent castability. It responds well to plating, painting, and chromate treatments. Limitations include potential dimensional changes when exposed to high temperatures.

Uses

Zamak 3 is manufactured through die casting and is widely used in automotive, electronics, and construction industries due to its exceptional damping capacity and vibration attenuation properties. Its tensile strength ensures durability under stress, while ductility allows for complex shapes without cracking. The alloy is also valued for its recyclability.
