Then again, it may be that the Captain purposely used softer Aluminum rivets as a safety so they would sheer before anything else broke. Kind of like a sheer pin on an (older) outboard motor prop. Several of us have posited that idea, although I don't think we've gotten a definitive reply from someone like Olivier Beaute. In any case, it seems a reasonable and conservative approach rather than harder stuff like monel and stainless steel Allen screws. (Yes, I did read the posts that Amel Matinique is using the ss Allen screws. Lots of ways to skin a cat, I guess.)

If you use rivers monel are the best. Inert. That is no corrosion and very strong, Ali are far too soft and sheer easily.

Stainless screws are fine if you use something like Tefgel to isolate them.
Even if you do go with aluminum screws, use Tefgel. The difference in alloys is enough to cause trouble, and the Al screws are not strong enough to remove if there is even a trace of corrosion. Talk to anybody who head had to remove the Al screws Amel used to attach the boom tracks!
