Zamak 2

Zinc Alloy 2 (ASTM AC43A), also known as Kirksite or Zamak 2, 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
