From Wikipedia, the free encyclopedia

Zamak (formerly trademarked as ZAMAK[1] 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 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] The New Jersey Zinc Company developed zamak alloys in 1929. While zinc alloys are popularly referred to as pot metal or white metal, zamak is held to higher industrial standards.
