Zamak 2
Zinc Alloy 2, also known as Kirksite or Zamak 2 (ASTM AC43A), is the highest strength and hardness of the Zamak family. This alloy has excellent casting characteristics including:
- A higher creep performance than other Zamak alloys
- Excellent damping capacity and vibration attenuation in comparison to aluminum die cast alloys
- High strength and hardness levels after long-term aging
