Zamak is one of the most widely used non-ferrous alloys thanks to its combination of mechanical properties, dimensional stability, and cost-effectiveness. However, what many professionals in the industry don’t know is that, in its early days, this alloy was also known by other names: zamak and mazak. This alternative name, although less common today, has a historical origin that we’re sure you’ll find interesting.
As we explained on another occasion when addressing the differences between zamak and zamac, the linguistic nuances around this alloy are not merely a matter of terminology, but rather stem from technical, historical, and even regulatory contexts. In this new article, we go one step further to focus on another of the names that accompanied zamak throughout its development: Mazak.
Far from being an error or a confusion, the name Mazak was part of the process of defining and standardising zinc-aluminium alloys in the 20th century. This terminological curiosity, which may seem anecdotal, actually reflects a key stage in the history of materials engineering.
Mazak: a historical name
At the end of the 1920s, the New Jersey Zinc Company, based in the United States, developed a new family of zinc-based alloys containing small proportions of aluminum, magnesium, and copper. The goal was to improve the properties of cast zinc, traditionally used in industry but limited by its brittleness and dimensional instability. These new alloys were much more resistant and better suited for high-precision die casting processes.
During the early years of development, these alloys were referred to in different ways. There are historical references to the names “Zama” and “Mazak” as initial terms. Eventually, the company decided to standardize the name as Zamak, using the initials of the main elements in German:
Z = Zink (zinc)
A = Aluminium (aluminum)
MA = Magnesium (magnesium)
K = Kupfer (copper)
Thus, the name zamak not only reflected its composition but also helped differentiate these alloys from other similar metals, such as pure zinc or tin alloys.
So… why does the term “mazak” still persist?
Although “zamak” is today the most widely accepted term, the word mazak has not disappeared entirely. In some older technical documents or specific industrial contexts—especially in English-speaking countries or Eastern Europe—mazak is still used as a synonym for zamak.
There has also been some confusion due to the coincidence with Yamazaki Mazak Corporation, a Japanese CNC machinery manufacturer. However, in the context of metal alloys, mazak has no relation to that company: its use predates it and is strictly technical.
Technical properties of zamak (or mazak)
Beyond its name—zamak or its older variant mazak—this alloy stands out for several key technical advantages. One of the most relevant is its excellent behavior in casting. Its high fluidity makes it possible to produce parts with complex geometries, thin walls, and precise finishes, making it ideal for high-pressure die casting.
In addition, zamak offers excellent dimensional stability and mechanical strength. Parts maintain their shape even under demanding conditions and withstand tension and compression well, ensuring long-term reliability.
As for subsequent processes, zamak is easy to machine and allows for finishes such as chrome plating, powder coating, nickel plating, or lacquering, making it an excellent option for visible or decorative components.
Another strength is its cost-effectiveness. Compared to other alloys like aluminum or brass, zamak offers a better cost-performance ratio, which explains its use in industries such as automotive, hardware, electronics, and household goods.
Finally, it is a recyclable material, which aligns with the principles of the circular economy. Its ability to be reused without significant loss of properties makes it an increasingly sustainable choice.
At Jegan, we know the value behind the name
At Jegan, we have been working with zamak alloys for decades, and we understand not only their technical performance but also the history and evolution of this material. We know that behind a name like zamak—or mazak—there is a process of research, standardization, and continuous improvement that has made it possible to produce high-quality parts that are strong, aesthetic, and functional.
Our commitment is not only to the material itself, but also to its correct application and transformation. That is why we ensure that our parts meet the most demanding market standards and provide our clients with personalized technical support from the design stage to final delivery.
At Jegan, we believe that understanding the origin and properties of a material is just as crucial as mastering its precise shaping. And that is what sets us apart.
