Zinc is one of the most popular metals for die casting (especially hot-chamber die casting) for several key reasons:

Most Common Zinc Die-Casting Alloys

a.Zamak 3 – the “standard” alloy (excellent balance of properties and castability)

b.Zamak 5 – slightly higher strength and hardness

c.ZA-8, ZA-12, ZA-27 – higher aluminum content → higher strength and creep resistance (often used in larger or structural parts)
