EZAC® is the most recent development in the family of zinc die casting alloys. Research has shown EZAC® to be the most creep resistant of all the zinc die casting alloys with over an order of magnitude improvement over the standard zinc die casting alloys like Zamak 3 and ZA-8. It is also the strongest (57 ksi) and hardest alloy (120 Brinell), with the advantage of being a hot chamber alloy due to its lower melting temperature. We have also found EZAC® to be one of the most fluid zinc die casting alloys, and have successfully die cast thin wall components with a wall thickness of 0.19 mm (0.0075").

EZAC® is a zinc-based alloy with specific additions of copper and aluminum. It is this proprietary and unique combination of elements that give this alloy its improved strength, hardness and creep performance. A certificate of conformance is available upon request.
