TUAL0.12
1 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations
Mass fraction wt%; GB/T 5231-2012, Table 1, row 31, designation T15700; original scan PDF page 5 (printed page 3). 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. Cu is the balance; Al2O3 refers to the alumina content and must not be mistaken for the element Al range.
