Zamak 12 / Zinc Alloy 12 / ZL 12/ ZnAl11Cu1
Zamak 12 is the best gravity casting alloy for sand, permanent mold and the graphite mold casting process. It is also a good (cold chamber) die casting alloy.
ZA-12 is the most versatile zinc alloy in terms of combining high performance properties and ease of fabrication using either gravity or pressure die casting
For these reasons, die cast ZA-12 often competes with ZA-27 for strength application. An excellent bearing alloy, ZA-12 is also palatable, although plating adhesion is reduced compared to the zinc alloys
