ZA alloys represent a new family of zinc-based die casting materials that contain higher aluminum content than standard zinc
alloys. These alloys provide high strength characteristics plus high hardness and good bearing properties (Table 2). Thin wall
castability characteristics and die life are similar to zinc alloys. ZA-8 is recommended for hot chamber die casting. ZA-12 and ZA-
27 must be cast by the cold chamber die casting process. All ZA alloys offer similar creep properties and are superior to standard
zinc alloys.
ZA-8 -- Provides strength, hardness and creep properties.
ZA-12 -- Provides excellent bearing properties with strength and hardness characteristics between ZA-8 and ZA-27. Good
dimensional stability properties and somewhat better castability than ZA-27.
ZA-27 -- Offers the highest mechanical properties of the ZA family and is therefore recommended when maximum performance is
required.
