7049A
2 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 |
|---|---|
| Si | ≤ 0.4 (lower limit not stated) |
| Fe | ≤ 0.5 (lower limit not stated) |
| Cu | 1.2 ～ 1.9 |
| Mn | ≤ 0.5 (lower limit not stated) |
| Mg | 2.1 ～ 3.1 |
| Cr | 0.05 ～ 0.25 |
| Zn | 7.2 ～ 8.4 |
| Ti | ≤ 0.06 (lower limit not stated) |
Applicability and limitations
Table 2 coupled limit: Zr+Ti<=0.25 (mass percent); this must be satisfied together with all individual limits. ; Al is the balance; no independent numerical minimum is specified; Subtracting listed maxima from 100% must not be used to invent a minimum. ; Each otherwise unlisted element is ≤0.05%; this is not automatically treated as a known limit for a specific element. ; The combined total of otherwise unlisted elements is ≤0.15%. ; Table 1 applicable forms: extruded bars and cold-drawn bars; Form codes correspond only to Table 1 of this edition and do not establish supply by Creation Group. ; Table 2 gives chemical composition in mass percent; Mechanical properties, dimensions and delivery condition require separate verification against the applicable original tables and order requirements.
