Which of the following metals is commonly used in die casting?

Zinc is commonly used in die casting due to its favorable properties for this process. It has a relatively low melting point, which allows for easy melting and fast processing. This makes it particularly well-suited for creating complex shapes with high precision. Additionally, zinc has excellent fluidity, which ensures that it fills the intricate molds used in die casting, resulting in smooth finishes and tight tolerances.

Moreover, zinc die castings exhibit good corrosion resistance, making them suitable for various applications, including automotive parts, hardware, and consumer products. The mechanical properties of zinc also allow for sufficient strength and durability, further enhancing its suitability for die casting applications. Thus, the combination of ease of processing, good fluidity, and desirable mechanical properties make zinc a preferred choice in the die casting industry.
