Composition of casting zamak

Zinc alloys foundry under pressure are the most common zamak zamak 3 and 5. They are transformed into hot chamber die casting. Other alloys with higher aluminum content (ZA8, ZA12, ZA27, ...) are much less used.

Terms zamak 3, Zamak 5 ZA8, ZA12 and ZA27 are very commonly used worldwide in both Europe and the US. The name zinc alloys (foundry under pressure) is more "standardized" global than that of aluminum alloys (Al Si9Cu3 A380 in Europe and the USA). Probably due to a greater historical age of the industrial use of zinc alloys.
