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 3, row 63, designation T68210; 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 k: the range 0.05–0.9% is for combined Ni+Fe+B, not for Ni alone. Table 3, note c: total impurities are the sum of measured contents of the impurity elements listed in the table.
