What you have asked is less than a complete question. In order to talk
about corrosion you must fully specify both the material (substrate
and coatings) and the service environment. Is the material pure
aluminum, or is it an alloy? If it is an alloy, what alloy? What else
is in the service environment other than water? Chlorides, sulfates,
I suspect that what you are asking is for the pH range over which
aluminum will be passive.
The best online textbook on aluminum alloys (and including their
corrosion behavior) is Talat
See section 5102.04 for the Pourbaix diagram showing that at room
temperature a passive film could be stable over a pH range from 4.0 to
8.5. However, you are not at room temperature.
Some nuclear reactor fuel was aluminum clad. An IAEA publication
discusses corrosion of spent fuel.
Look at chapter 2.
We do not believe what we write, and neither should you. Information
furnished to you is for topical (external) use only. This information
may not be worth any more than either a groundhog turd, or what you
paid for it (nothing). The author may not even have been either sane
or sober when he wrote it down. Do not worry, be happy.
