Quick Summary

The ZA series refers to a group of high-performance zinc-aluminum casting alloys that emerged from research since the late 1960s. These alloys offer improved properties compared to traditional zinc alloys.1

Key alloys in the ZA series include:
* ZA 8: Used for gravity-cast parts needing better creep resistance and is suitable for electroplating.1
* ZA 12: A general-purpose alloy suitable for sand casting, permanent-mold casting, and cold-chamber pressure die-casting.1
* ZA 27: The strongest nonferrous alloy in this series, capable of pressure die-casting and extrusion.1

These alloys are part of zinc's broader applications, which include corrosion protection, brass alloys, and cast-zinc alloys used in industries like automotive and domestic appliances.12
