Let Eastern Alloys assist you in determining the correct Zinc die casting alloy for your component. Please use the filter on the left by choosing the yearly volume requirements and properties that best suit the part being designed. The alloy choices (below) will be filtered to help you select the most appropriate alloy. For further discussion on these alloys, please give us a call to discuss.
The most common zinc die casting alloy in North America. Usually the first choice when considering an alloy for zinc die casting due to its excellent combination of mechanical and physical properties, and superb casting and finishing ability.
Commonly used zinc die casting alloy throughout the world due to its combination of strength, ductility and fluidity. The 1% additional copper added to the alloy improves the alloy's mechanical properties.
Within the Zamak family of zinc die casting alloys, Zamak 2 has the highest strength and hardness due to its higher copper content (3%). Also known as Kirksite when making tooling for the stamping or plastic injection mold industries.
Although magnesium is a useful element to combat corrosion effects of the alloy due to certain impurities, it was also found to reduce the alloy's fluidity. In this alloy, nickel replaced magnesium, which helped improve the fluidity and casting ability of the alloy. The properties are similar to Zamak 3 with enhanced fluidity.
A zinc die casting alloy developed in the 1990's by General Motors. ACuZinc is a zinc based alloy with approximately 5% copper and 3% aluminum. The combination AL/Cu/Zn in this alloy produces castings with exceptional mechanical and physical properties.
Zinc die casting alloy with the highest strength, hardness and creep resistance, along with exceptional fluidity.
Zinc alloy with 8% aluminum. The most common of the ZA alloys due to its combination of strength, casting ability (cast in a hot chamber machine), and is often electro-plated.
Zinc alloy with 27% aluminum. This higher aluminum content offers an alloy with exceptional mechanical properties as well as the lowest density of all the zinc die casting alloys.
ZA-12 has an excellent combination of mechanical properties and casting ability. Due to its elevated aluminum content this alloy is cast in a cold chamber die casting machine.
Zinc/Aluminum alloy with 8% aluminum. ZA-8 can be both gravity cast and die cast. The lower aluminum content allows this alloy to be easily electro-plated.
ZA-12 is a zinc based casting alloy that can be both gravity cast and die cast. It is the most common gravity casting alloy with the best combination of properties and casting ability.
Zinc/Aluminum alloy with 27% aluminum. ZA-27 can be both gravity cast and die cast, and is the strongest of the ZA alloys.
A moderate strength zinc-based alloy developed primarily as a forming tool alloy.
Zinc based alloy used to form "hollow" decorative castings that are not subjected to high stress conditions.
