Zamak

Zamak or Zamac
(once trademarked as ZAMAK)

A family of zinc alloys with: aluminium, magnesium, and copper.
New Jersey Zinc Company developed zamak alloys in 1929

The name zamak is an acronym of the German names for the metals in the alloy:
Zink (zinc)
Aluminium
Magnesium
and
Kupfer (copper)

Zamak alloys are zinc / aluminium alloys distinguished by 4% aluminium

Zinc alloys are referred to as; pot metal or white metal
Zamak has higher (industrial) standards

The most common zamak alloy is:
zamak 2 (greatest strength)
zamak 3 (North America)
zamak 4 (Asia, Japan)
zamak 5 (Europe)
zamak 7 (casting thin wall components)

commonly die cast
spin casting industry (#3 and #5)

Zamak 2 = zamak 3 + 3% copper
Zamak 3 = the standard
Zamak 4 = zamak 3 + 0.5% copper
Zamak 5 = zamak 3 + 1% copper
Zamak 7 = zamak 3 w/ less magnesium

Zamak can be: electroplated, wet painted, and chromate coated

10x J-22 .22lr pistol Function Test

Took a few J-22 Pistols to the range for function testing

These are all just as they were when I bought them, some are brand new, some are used and need a regular cleaning, and some are REALLY neglected and need a good cleaning
