ZAMAK

What is ZAMAK?
Zinc, the fourth most used metal in the world metal market, is the 27th most abundant element in the earth's crust.

Zamak alloy, on the other hand, is a material that can be called a zinc alloy because it contains mostly zinc, consisting of zinc, aluminum, magnesium and copper.

Zamak was found in the United States in the 1920s. Found by The New Jersey Zinc Company, Zamak takes its name from the initials of German zinc (Zink), aluminum (Aluminium), magnesium (MAgnesium) and copper (Kupfer).

It is an extremely durable alloy that is resistant to breaking, stretching and breaking.

Its production is also very common in Turkey and it is produced mostly by India and China in the world.
Zamak takes names such as zamak 7 – zamak 12 according to the proportions of the main components in it.

These names also provide an insight into the hardness of the alloy.

Zamak is a flexible and durable material that is resistant to impacts. With injection and centrifuge methods, zamak, which is in liquid state at approximately 400ºC, is formed by cooling together with steel molds and model tires in zamak casting machines.

Zamak Production Processes
Zamak production generally takes place in two stages. These are Hydrometallurgical and Pyrometallurgical processes.
