ZA alloys are a group of zinc-based alloys that include aluminum and copper as primary alloying elements. They are known for their excellent casting properties, high strength, and good corrosion resistance. These alloys are commonly used in die casting applications, making them suitable for producing complex shapes and components in various industries. The most popular types of ZA alloys are ZA-8, ZA-12, and ZA-27, each with different compositions and properties. These alloys are often chosen for their lightweight nature and ability to be easily machined, making them ideal for automotive, aerospace, and consumer product applications.
