context_page_description: Zamak 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 aluminum alloy family; they are distinguished from the other ZA alloys because of their constant 4% aluminium composition.
  The name zamak is an acronym of the German names for the metals of which the alloys are composed: Zink, Aluminium, Magnesium and Kupfer. The New Jersey Zinc Company developed zamak alloys in 1929. Zinc alloys are popularly referred to as pot metal or white metal. While zamak is held to higher industrial standards, it is still considered a pot metal.
  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 alloys are frequently used in the spin casting industry.
  A large problem with early zinc die casting materials was zinc pest, owing to impurities in the alloys. Zamak avoided this by the use of 99.99% pure zinc metal, produced by New Jersey Zinc's use of a refluxer as part of the smelting process.
  Zamak can be electroplated, wet painted, and chromate conversion coated well.
