QAL6
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.

Composition
| Element | Composition requirement |
|---|---|
| Al | 5.0 ～ 6.5 |
| Fe | ≤ 0.1 (lower limit not stated) |
| Pb | ≤ 0.1 (lower limit not stated) |
| As | 0.02 ～ 0.35 |
Applicability and limitations
Mass fraction wt%; GB/T 5231-2012, Table 4, row 25, designation C60800; scanned PDF, PDF physical page 10. Cu is balance; dashes mean unspecified and are not replaced with zero. The total of table-listed impurities is ≤0.7%, subject to the applicable table notes. This standard provides the grade-composition basis for wrought copper and copper alloys; actual supply and cold-heading suitability require separate confirmation. Note a to Table 4: analysis of As, Sb and Bi may be omitted, but the supplier must ensure that their contents do not exceed the table limits.
