Zamak 3

Zamak 3 (ASTM AG40A), or Zinc Alloy 3, is the most widely used zinc alloy in North America and is usually the first choice when considering zinc for die casting for a number of reasons.

  • Excellent balance of desirable physical and mechanical properties
  • Superb castability and long-term dimensional stability
  • Excellent finishing characteristics for plating, painting, and chromate treatments
  • Excellent damping capacity and vibration attenuation in comparison to aluminum die cast alloys

When it comes to die casting, Zamak 3 is the standard by which other zinc alloys are rated.
