NECKLACE IN ZAMAK (zamak)

The term zama metal alloy refers to a family of zinc alloys, whose main elements are aluminum, magnesium, antimony, and copper. The second alloying element is aluminum, which is present in percentages ranging from 0.8% to 27%, and its main effect is that of a hardening agent, while copper increases castability.

Iron is present as an impurity.

'The excellent fluidity and hardness comparable to that of many cast irons and brasses make Zama suitable for jewelry.'
