It is Made from pure Zinc Alloy so it is rust free and provides long life.
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 4%
aluminium composition.
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).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.[2] These alloys are
most commonly die cast.Zamak alloys (particularly #3 and #5) 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.
In the early 1930s Morris Ashby in Britain had licensed the New Jersey zamak alloy. The high-purity refluxer zinc was not available in Britain and so they acquired the right to manufacture the alloy using a locally available electrolytically refined zinc of 99.95% purity. This was given the name Mazak, partly to distinguish it from zamak and partly from the initials of Morris Ashby. In 1933, National Smelting licensed the refluxer patent with the intent of using it to produce 99.99% zinc in their plant at Avonmouth.
