Eastern Alloys manufactures the complete range of ZAMAK alloys
developed for the die casting process. ZAMAK alloys were first developed during
the 1920's by The New Jersey Zinc Company. The name ZAMAK draws upon the basic
metallurgy of the alloy group: Z-Zinc, A-Aluminum, MA-Magnesium, and K-Kopper
(e.g., German). In the United States, ZAMAK 3 is the most common alloy for hot
chamber die casting. With a combination of superior mechanical properties and
low melting/manufacturing costs, it fulfills the needs for most die casting
applications. Other ZAMAK alloys include ZAMAK 2, ZAMAK 5, and ZAMAK 7. Common
to each alloy is a consistent Aluminum content range, however, the alloys
differ in specification by varying amounts of copper, magnesium, and nickel -
resulting in different mechanical and physical properties.
