Salt or Fresh, Tropical, arctic.....? What use, mechanical load,
vibration, stress, compression, tension, torsion...etc?

Sal****er, and for use as a grounding plate for an SSB radio.

There is a sintered bronze product called a Dynaplate designed for
that purpose:

(search for dynaplate)

Be careful here. Bronze may not be the best choice. Please keep in mind
dissimilar metals that could cause electrolysis. Bronze all by itself may
live quite happily for hundreds of years by itself, but with other metal
objects could cause serious corrosion to itself and other objects attached
to the boat. So, what else is attched to the boat and underwater?

I think the only real issue is corrosion resistance. As for strength
some bronze is stronger than mild steel. As much as 100 000 PSI, if I
recall correctly v. 30 000 for cheap steel. Don't you usually just buy
what is available? Trust them to use something suitable? I would bet
the stainless used for props is much stronger than coathanger steel.
They do make guns from stainless, and and the stuff used is as strong
as the chrome moly used forever. Stronger than the bronze used for
props if you go by the thinner sections used. I think just about
anything will be OK but I don't know for sure. Get US made stuff, I
wouldn't trust Chinese products.

I can't agree with you.
Many American companies deal in Chinese products for years
and gain many profit.If they won't sell bronze fasteners from
Yushung in China,they will be difficult to find similar another
supplier of bronze fasteners.
