TAG0.1

Mass fraction wt%; Under 2.2, elements with specified lower and upper limits are alloying constituents; a single value is a minimum for copper and a maximum for other elements. A dash means unspecified; it is not entered as zero; Cu+Ag and Ni+Co are subject to combined ranges and are not converted into independent element ranges. The balance remains a balance; subtracting independent maxima does not establish a guaranteed range. Total impurities include all relevant impurities; The sum of listed elements is only a necessary condition and cannot replace complete impurity analysis. Product forms in the original document define the applicable wrought-product scope; they do not establish confirmed supply of cold-heading wire or final properties.

Mass fraction wt%; GB/T 5231-2012, Table 1, row 17, designation T11210; original scan PDF page 5 (printed page 2). A dash indicates that the value is unspecified and shall not be treated as zero; The combined lower limit shall not be split into independent lower limits for each element. Standard Clause 2.2: Impurities listed as a single value in the table are maximum limits; Limits for elements not listed cannot be supplemented as zero by referring to other versions. Table 1 Note a: As, Bi, and Sb may not be analyzed, but the supplier must guarantee that they do not exceed the upper limits listed in the table. This standard only specifies the grades and chemical compositions of wrought copper and copper alloys; actual supply of cold heading wire shall not be inferred therefrom. Table 1 Note h: This value is the copper content. Table 1 Note h: 99.5% is the lower limit for copper content, not the combined lower limit for Cu+Ag.
