Abstract
Disclosed herein is an aluminum alloy that is both age-hardenable and degradable in water-containing fluids. Some embodiments include aluminum alloy compositions with about 0.5 to 8.0 wt. % Ga (Gallium); about 0.5 to 8.0 wt. % Mg (Magnesium); less than about 2.5 wt. % In (Indium); and less than about 4.5 wt. % Zn (Zinc).
Claims19
An age hardenable and water degradable aluminum alloy, comprising:
- a. about 0.5-8.0 wt. % Ga;
- b. about 0.5-8.0 wt. % Mg;
- and
- c. about 0.1-2.1 wt. % In, wherein said alloy is subjected to solution annealing and further age hardening in order to form fine precipitates.
