EZAC

Dynacast partners with Eastern Alloys Inc, to offer you EZAC. This hot chamber zinc alloy has superior creep resistance, high yield strength, high hardness, and low melting temperatures.
The EZAC alloy provides superior creep resistance, higher yield strength, and higher hardness when compared with other zinc alloys. EZAC performs approximately fourteen times longer than Zamak 2 and three times longer than ACuZinc5 in creep resistance tests at 140C and 31MPa, achieving 730 hours.

While zinc has always been known for its high strength, the addition of the Zamak family, and now EZAC, make hot chamber die casting zinc alloys even more suitable for multiple applications. Before EZAC, zinc was often overlooked for applications requiring high tensile strength and more specifically high-temperature tensile strength. Additionally, most zinc alloys have a low creep resistance when compared with other materials. These areas of improvement were the focus when creating EZAC.

Comparing EZAC to Other Die Casting Alloys

In regards to yield strength, EZAC is comparable to ZA-27, which is the strongest cold chamber zinc die cast alloy. With a yield strength of 396 MPa—stronger than any other hot chamber zinc die cast alloy, EZAC achieves a 42% improvement over Zamak 2 and a 19% improvement over ACuZinc5. The hardness of EZAC also shows a 19% improvement over Zamak 2 and 11% improvement compared to ACuZinc5.
