GB/T 5153-2016 Designation and composition of wrought magnesium and magnesium alloys
1 Scope
This standard specifies the designations and chemical compositions of wrought magnesium and magnesium alloys.
This standard is applicable to wrought magnesium and magnesium alloy products.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 8170 Rules of rounding off for numerical values & expression and judgment of limiting values
GB/T 13748 (all parts) Chemical analysis methods of magnesium and magnesium alloys
GB/T 17432 Methods for sampling for analyzing the chemical composition of wrought aluminum and aluminum alloys
ISO 3116:2007 Magnesium and magnesium alloys - Wrought magnesium alloys
3 Designation naming rules
3.1 Pure magnesium designations are expressed in the form of Mg followed by a number, where the number after Mg indicates the mass fraction of Mg.
3.2 Magnesium alloy designations are expressed in the form of English letter(s) followed by number(s) and then another English letter. The preceding English letter(s) represent the code(s) of the principal alloying element(s) (element codes shall meet those specified in Table 1), the following number(s) indicate the approximate content(s) of the principal alloying element(s), and the final English letter is an identification code used to distinguish different alloys that differ in specific constituent elements or have slight differences in element content.
