Foreword
This Standard modifies and adopts ASTM B 179-06, Standard specification for
aluminum alloys in ingot and molten forms for castings from all casting processes.
Compared with ASTM B 179-06, the differences of this Standard with respect to main
technical contents are as follows.
-- significant editorial modifications are made in structure;
-- the normative references in Clause 2 of ASTM B 179-06 are not used;
-- the ordering information of and electrical conductivity requirements for die casting
aluminum alloys in Clauses 3 and 9 of ASTM B 179-06 are not used;
-- Annex A to ASTM B 179-06 are not used;
-- new Annexes A, B and C are added.
This Standard replaces GB/T 15115-1994, Die casting aluminum alloys.
Compared with GB/T 15115-1994, the main technical content changes of this Standard
are as follows.
-- in chemical composition, it modifies the contents of Fe and Mg and the content
of Zn in YLAlSi9Cu4;
-- it adds the material designation YZAlSi10Mg (YL101) and deletes the material
designation YZAlSi12Cu2 (YL108);
-- it cancels the mechanical property values in technical requirements, which are
not deemed as the criteria for acceptance of die casting aluminum alloys;
-- Annexes A, B and C are added.
Annexes A, B and C are informative.
This Standard was proposed by the China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee 54 on
Foundry of Standardization Administration of China (SAC/TC 54).

3 Designations and codes of alloys
3.1 Representation of alloy designations
Designation of die casting aluminum alloys consists of chemical symbols of aluminum
and major alloy elements. Major alloy elements are followed by digits showing their
nominal mass fraction (nominal mass fraction is the rounded off integer values of the
mean mass fraction of the elements).
“YZ” (“Y” and “Z” are the first letters of two Chinese characters’ pinyin “Ya” and “Zhu”)
aluminum designations represent a die casting alloy.
3.2 Representation of alloy codes
In alloy codes, “YL” (“Y” and “L” are the first letters of two Chinese characters’ pinyin
“Ya” and “Lv”) represent a die casting aluminum alloy. The first digit behind YL, i.e. 1,
2, 3 and 4, represents respectively Al-Si, Al-Cu, Al-Mg and Al-Sn serial alloys, which is
the code of the alloys. The second and third digits after YL are sequence numbers.
4 Technical requirements
Chemical compositions of die casting aluminum alloys shall be as specified in Table 1.
