Definitions
- Aluminum alloys are useful in a variety of applications. However, improving one property of an aluminum alloy without degrading another property is elusive. For example, it is difficult to increase the strength or corrosion resistance of a wrought 7xxx aluminum alloy without affecting other properties.
- a new wrought 7xxx aluminum alloy includes at least 1.35 wt. % Mg. In another embodiment, a new wrought 7xxx aluminum alloy includes at least 1.40 wt. % Mg. In yet another embodiment, a new wrought 7xxx aluminum alloy includes at least 1.45 wt. % Mg. In another embodiment, a new wrought 7xxx aluminum alloy includes at least 1.50 wt. % Mg.
- the combined amount of zinc and magnesium in a new wrought 7xxx aluminum alloy is not greater than 6.50 wt. % (i.e., wt. % Zn + wt. % Mg ⁇ 6.50 wt. %). In another embodiment, the combined amount of zinc and magnesium in a new wrought 7xxx aluminum alloy is not greater than 6.25 wt. % (i.e., wt. % Zn + wt. % Mg ⁇ 6.25 wt. %). In yet another embodiment, the combined amount of zinc and magnesium in a new wrought 7xxx aluminum alloy is not greater than 6.00 wt. % (i.e., wt. % Zn + wt.
- a new wrought 7xxx aluminum alloy includes not greater than 0.90 wt. % Cu. In yet another embodiment, a new wrought 7xxx aluminum alloy includes not greater than 0.85 wt. % Cu. In another embodiment, a new wrought 7xxx aluminum alloy includes not greater than 0.80 wt. % Cu. In one embodiment, a new wrought 7xxx aluminum alloy includes at least 0.40 wt. % Cu. In another embodiment, a new wrought 7xxx aluminum alloy includes at least 0.45 wt. % Cu. In yet another embodiment, a new wrought 7xxx aluminum alloy includes at least 0.50 wt. % Cu. In another embodiment, a new wrought 7xxx aluminum alloy includes at least 0.55 wt. % Cu. In yet another embodiment, a new wrought 7xxx aluminum alloy includes at least 0.60 wt. % Cu.
- the new wrought 7xxx aluminum alloys generally include from 0.06 to 0.20 wt. % Zr. As shown by the below data, the combination of vanadium and zirconium may facilitate, for instance, improved fatigue failure resistance properties.
- a new wrought 7xxx aluminum alloy includes not greater than 0.18 wt. % Zr.
- a new wrought 7xxx aluminum alloy includes not greater than 0.16 wt. % Zr.
- a new wrought 7xxx aluminum alloy includes not greater than 0.15 wt. % Zr.
- a new wrought 7xxx aluminum alloy includes not greater than 0.14 wt. % Zr.
- the total amount of vanadium plus zirconium should be controlled to restrict formation of a high volume fraction of constituent particles (e.g., a high volume fraction of Al 3 Zr, AI23V4, AI 7 V and/or A1 10 V constituent particles).
- the total amount of vanadium plus zirconium does not exceed 0.23 wt. % V + Zr.
- the total amount of vanadium plus zirconium does not exceed 0.22 wt. % V + Zr.
- the total amount of vanadium plus zirconium does not exceed 0.21 wt. % V + Zr.
- the total amount of vanadium plus zirconium does not exceed 0.20 wt.
- the quench insensitivity of the new wrought 7xxx aluminum alloys may facilitate improved strength. Likewise, when using a hot quench media, a new wrought 7xxx aluminum alloy may realize less distortion.
- the new wrought 7xxx aluminum alloys may be post-solution heat treatment quenched with any applicable fluid or media.
- a new wrought 7xxx aluminum alloy is water quenched (cold water quenched, hot water quenched, or boiling water quenched).
- the new wrought 7xxx aluminum alloy is hot or boiling water quenched.
- a hot water quench is a quenching using water having a temperature of from 150°F to boiling (212°F at standard temperature and pressure).
- a boiling water quench uses boiling water.
- a boiling water quench is a species of the hot water quench genus. As shown by the below data, use of a hot water quench (including a boiling water quench) may facilitate improved SCC resistance.
