Improved 5xxx aluminum alloys and products made therefrom are disclosed. The new 5xxx aluminum alloy products may achieve an improved combination of properties due to, for example, the presence of copper. In one embodiment, the new 5xxx aluminum alloy products are able to achieve an improved combination of properties by solution heat treatment.

5XXX aluminum alloys and wrought aluminum alloy products made therefrom

Aluminum alloy products having improved ballistics performance are disclosed. The aluminum alloy products may be underaged. In one embodiment, the underaged aluminum alloy products realize an FSP resistance that it is better than that of a peak strength aged version of the aluminum alloy product. In one embodiment, ballistics performance criteria is selected and the aluminum alloy product is underaged an amount sufficient to achieve a ballistics performance that is at least as good as the ballistics performance criteria.
