Zamak
brand of zinc alloys
ZAMAK (or Zamac, formerly trademarked as MAZAK) is a family of alloys with a base metal of zinc and alloying elements of aluminum, 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% aluminum 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.
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 (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 refining-process.
“Zamak” enters the record as brand of zinc alloys. Crown Archives preserves that source wording while asking what Zamak, brand and zinc can confirm, complicate or overturn.
Why this record matters
“Zamak” is worth following because a concise public description often conceals a longer documentary argument. Here, Zamak, brand and zinc provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q145352. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1929.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
