Zamak Chemical Composition Comparison
Zamak (formerly trademarked as ZAMAK and also known as Zamac is a family of alloys with a base metal of zinc and alloying elements of aluminium, magnesium, and copper.
Zamak alloys are part of the zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 5% aluminium composition.
The most common zamak alloy is zamak 3. Besides that, zamak 2, zamak 5 and zamak 7 are also commercially used. These alloys are most commonly die cast.
Zamak can be electroplated, wet painted, and chromate conversion coated well.
