Zamak alloys are part of the zinc aluminium alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition. [ 2 ] The name zamak is an acronym of the German names for the metals of which the alloys are composed: Zink (zinc), Aluminium , Magnesium and Kupfer (copper). [ 2 ]

Zinc pest (from German Zinkpest "zinc plague"), also known as zinc rot, mazak rot and zamak rot, is a destructive, intercrystalline corrosion process of zinc alloys containing lead impurities. [1] While impurities of the alloy are the primary cause of the problem, environmental conditions such as high humidity (greater than 65%) may accelerate ...
