| Sl.No. | Synosis Points | |
| 1 | title has been modified from ‘Zinc Base Alloy Ingots for Die Casting’ to ‘Specification of Zinc-Aluminium Alloy Ingots Intended for Foundry and Die Castings’ and Scope has been enlarged to include alloys intended for foundry castings and thin wall die castings. | |
| 2 | b) Seven new grades have been added to the standard, including two additional conventional Zamak alloys (Zamak 2 and Zamak 7), three new ZA alloys with a nominal composition exceeding 4 percent, one new high-fluidity alloy (HF alloys) designed for thin-wall die castings, and one more grade, ACuZn5, developed by General Motors. The ACuZn5 alloy features a slightly higher copper content and offers improved tensile strength, hardness, and creep resistance compared to the Zamak alloys. Its strength, hardness, and wear properties are comparable to those of ZA-12. | |
| 3 | c) Small compositional changes have been made in ZnAl4 (Zamak 3) and ZnAl4Cu1 (Zamak 5), including the removal of Indium and Thalium requirements in the composition to align with international standards | |
| 4 | f) Informative Annexes A, B, C, and D have been incorporated into the standard. Annex A delineates the relationship between the alloy designations specified in this standard and those employed in other international and national standards. Annex B provides a detailed overview of the nomenclature systems for zinc and zinc-aluminium alloys. Annex C offers comprehensive information regarding the development of advanced high-fluidity alloys, furnishes guidance on the selection of appropriate zinc alloys for specific applications, and elaborates on the role of various alloying elements in zinc alloys for die casting. Annex D includes information on the generally available composition of master alloys used with Zn99.995 and Zn99.99 grades of IS 209 for producing zinc alloy ingots for foundry and die casting applications. | |
