Applicability and limitations

Mass fraction wt%; GB/T 5231-2012, Table 3, row 67, designation T68360; Scanned PDF, page 9. Zn is the balance; A dash means unspecified; it is not entered as zero. Clause 2.2: single tabulated impurity values are maxima. Tabulated total impurities ≤0.3%; verify using measured contents of the impurity elements specified in the standard. This standard provides composition designations for wrought copper and copper alloys; actual supply and cold-heading suitability require separate confirmation. Table 3, note e: the range 0.05–1% is for combined Sb+B+Ni+Sn, not for Ni alone.
