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.
