Foreword
This Standard modifies and adopts ISO209.2007 "Wrought Aluminium and Aluminium
Alloy - Chemical Composition" (English edition), and it is redrafted in accordance with
ISO209.2007. For ease of comparison, the list of corresponding chapters and sections
between the International Standard and this Standard is detailed in Annex B (Informative).
Modifications are done while adopting the International Standard. the technical differences
are marked with vertical single-line on the page margin of the involved articles; they are as
follows.
— Delete the designation and composition of aluminium and aluminium alloy that have
not been produced in China ever;
— Delete the table of comparison between new and old designations in the ISO
standard;
— Add four-letter designation and composition that are special in China;
— Add the requirements for special control of toxic and harmful elements;
— Add the requirements on composition analysis and sampling.
This Standard replaces GB/T3190-1996 "Wrought Aluminium and Aluminium
Alloy-Chemical Composition". Compared with GB/T3190-1996, the main revisions in this
Standard are as follows.
— Add designations and compositions of 130 aluminiums and aluminium alloys; divide
the Table of chemical composition into two parts (two tables). Table 1 is applicable
to international designations, covering 159 designations; Table 2 is applicable to
four-letter designations, covering 114 designations;
— Add the requirements for special control of toxic and harmful elements;
— Add the denotation (method) of limit value;
— Revise "Table of Comparison between New and Old Designations".
Annex A and Annex B of this Standard are informative.
This Standard was proposed by China Non-ferrous Metals Industry Federation.
This Standard shall be under the jurisdiction of the National Standardization Technical
Committee of Non-ferrous Metal.

Wrought Aluminium and Aluminium Alloy –
Chemical Composition
1 Scope
This Standard specifies the chemical composition of wrought aluminium and aluminium
alloy.
This Standard is applicable to aluminium and aluminium alloy products (plate, strip, foil,
pipe, stick, section, line and forging) produced with press working, and cast ingot and
blanks used for them.
2 Normative References
The following standards contain the provisions which, through reference in this text,
constitute the provisions of this Standard. For the dated reference, the subsequent
amendments (excluding correction) or revisions of these publications do not apply.
However, the parties who enter into agreement according to these specifications are
encouraged to study whether the latest editions of these labels are applicable. For
undated references, the latest edition of the normative document is applicable to this
Standard.

aluminum alloys

3 Requirements
3.1 Chemical composition
3.1.1 The chemical compositions of wrought aluminiums and aluminium alloys shall meet
the requirements of Table 1 and Table 2. The column "others" indicates the metallic
element not listed in the table. For the contents in the table that are in
single-numerical-value, it is the minimal limit for aluminium; and it is the maximal limit for
other elements. The denotation of limit value is as.
Table 2 are suspected exceeding the limits of "single" or "total" values specified in this
Standard, then the manufacturer may do analysis for these elements.
3.3.4 When the content (mass fraction) of aluminium is larger than or equal to 99.00% and
less than 99.90%, it shall be determined by the calculation (method) that 100.00% is
deducted by the sum of the contents of all the elements of which the content is less than
0.010%. The content value of the elements shall be rounded to 0.0x% before summing.
3.3.5 When the content (mass fraction) of aluminium is larger than or equal to 99.00% and
less than or equal to 99.99%, it shall be determined by the calculation (method) that
100.00% is deducted by the sum of the contents of all the elements of which the content is
less than 0.0010%. The content value of the elements shall be rounded to 0.0XX% before
summing. The sum shall be rounded to 0.0X%.
3.3.6 The chemical components shall be analyzed by the method specified in GB/T 7999
or GB/T 20975, or other reliable and accurate method. in the case of dispute, the method
specified in GB/T 20975 or other method agreed by both parties must be adopted for
arbitration analysis.
3.3.7 If the first analytical results does not meet the requirements, second analysis may be
allowed; the second analytical result is deemed as the judgment basis for exit-factory of
the manufacturer and acceptance.
4 Others
4.1 The digit-number of element contents in chemical composition analytical report shall
be of correspondence to the one of the corresponding designation specified in Table 1 or
Table 2.
4.2 The rounding of numerical values shall meet the requirements of GB/T 8170.
4.3 The relation table of comparison for new and old designations is detailed in Annex A.
