Aluminum and zinc alloys are widely used in metal casting. However, alloy grades vary by country. In the United States, Germany, Japan, or China, the same material may be known as a completely different grade. This often leads to confusion in the international procurement and technical exchange process.
In order to assist engineers, buyers, and technical teams in determining the correct equivalent, we have compiled an international comparison table that lists the different grades of cast aluminum alloys and cast zinc alloys in major global standards such as ASTM, EN, JIS, ISO, etc.

In addition to aluminum alloy, zinc alloy is another popular choice in die casting, especially for smaller, high-precision components.
The Zamak family is particularly well-known, but each country applies its grade system to these alloys.
