Which Aluminum is best?

[vctech]

I am designing a pressure vessel for an submarine. Does anyone have any experience or suggestions with these alloys for this application?

Aluminum 5086 H111
Aluminum 5454 H111
Aluminum 5456 H111

Thanks

MIL-HDBK-5 does not speak to those aluminim alloys in regards to stress corrosion.
