Zamak is also known as Zamac which is composed of zinc and alloying elements of magnesium, aluminum, and copper. The Zamaks alloys were developed in 1929 by the New Jersey Zinc Company. Zamak 3 is the most common Zamaks alloy. Zamak 3 and 5 are often used for the spin casting industry.
Zamaks alloys can be used for locks, handles, automotive parts, bathroom fixtures, zippers, mirror frames, etc.
Every country defines zinc alloy composition differently, and you can see the following table for more information.
Zinc alloy standards in different countries
|Country||Zinc ingot||Zinc casting|
|USA||ASTM B240||ASTM B86|
|Canada||CSA HZ3||CSA HZ11|
|Australia||AS 1881-SAA H63||AS 1881-SAA H64|
|Japan||JIS H2201||JIS H5301|
Zamaks 3 is the standard for other zinc alloys, and other zinc alloy compositions are based on Zamaks 3 which is composed of 96% zinc and 4% aluminum
