Quick Summary

Alloy 5 is a zinc-based alloy primarily used in pressure die-casting. It is composed of high-purity zinc, aluminum, magnesium, and a small amount of copper, which makes it slightly harder than Alloy 3. This alloy is favored for its ability to be rapidly solidified under pressure into complex shapes with good dimensional stability and surface quality. These castings are frequently plated for decorative finishes and are utilized in various industries, including automotive for components and trim, as well as in domestic appliances, locks, and engineering parts.1
