Applicability and limitations
Mass fraction wt%; GB/T 5231-2012, Table 3, row 71, designation T69210; scanned PDF, PDF physical page 9. Zn is balance; dashes mean unspecified and are not replaced with zero. Clause 2.2: single impurity values in the table are maxima. The total of table-listed impurities is ≤1.3% and must be checked against measured values for the impurity elements specified in the standard. This standard provides the grade-composition basis for wrought copper and copper alloys; actual supply and cold-heading suitability require separate confirmation.
