Zamak: History and properties

At OLTEX Trading we are experts in the sale of beads and for this it is necessary that our materials are the best. For this reason, we work on the manufacture of these elements with Zamak, an alloy used for fittings and beads, among other uses, which we will explain their history and properties.

This alloy gets its name from the German acronym for the metals that make it up: Zinc (Zinc), Aluminum (Aluminum), Magnesium (Magnesium) and Kupfer (Copper).

THE HISTORY OF ZAMAK

This alloy was created by the New Yersey Zinc Company in the 1920s. In 1926 the first Zamak 1 alloy was patented that contains 4% aluminum, 3% copper and 0.1% magnesium, the remaining being high purity zinc . New Jersey Zinc Company filed additional patents on new Zamak 2, 3, 5, and 7 alloys. 1960 was when it began to be used industrially for large series of die casting zinc alloy processing.

However, it is worth remembering the discoveries in Greece, dating back to the 5th century BC, in which zinc bracelets were already found. From this we deduce that the first tests with these materials are really old.

ZAMAK PROPERTIES

It is not exactly a metal, but an alloy of the mentioned metals. Furthermore, the fusion of these metals turns out to be hypoallergenic and highly resistant to aging and oxidation. The material obtained, Zamak, has a high level of hardness and resistance to shocks.

It is a material with a high level of hardness and shock resistance, in addition to having a beauty and durability similar to silver, as it is bathed in it.

PRESENT HISTORY

We already know the history and properties of the Zamak. Currently, its use has been extended to hardware items, auto parts, and toy cars. Due to its aesthetic appeal and cheap manufacturing costs, the use of the Zamak in the metallic parts of accessories in leather has also increased. In addition, it allows a wide variety of designs. In the jewelery sector it is increasingly used, since it has great resistance and dirties less than silver.

At OLTEX Trading we work on the manufacture of these elements with Zamak, the alloy used for fittings and beads, among other uses, to provide the best results on our beads.
