Zamak

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. While zinc alloys are popularly referred to as pot metal or white metal, zamak is held to higher industrial standards.

The most common zamak alloy is zamak 3, but zamak 2, zamak 5 and zamak 7 are still commercially used. These alloys are most commonly die cast. Zamak alloys are frequently used in the spin casting industry..

Zamak can be electroplated, wet painted, and chromate conversion coated, all with very good results.
