Die casting is a manufacturing process that involves injecting molten metal into a mold, which then cools and solidifies to form a finished part. Aluminum and zinc alloys are commonly used in die casting due to their excellent strength-to-weight ratio, corrosion resistance, and ability to be easily machined.
However, different regions of the world may use different alloy specifications, which can cause confusion when trying to source materials or communicate with international suppliers. To help alleviate this issue, an Aluminum Alloy Specification Conversion Chart has been developed for international die cast manufacturing.
The chart lists the most commonly used aluminum and zinc alloy specifications, along with their equivalents in other regions.

In addition to the conversion chart, it is important to note that there may be slight variations in alloy composition and properties between different suppliers, even within the same region. Therefore, it is always recommended to work closely with suppliers and conduct testing to ensure that the desired material properties are achieved.
Overall, the Aluminum Alloy Specification Conversion Chart is a valuable tool for international die cast manufacturing, helping to streamline communication and ensure consistency in material specifications.
