Milton,

Naval bronze is a very strong copper alloy which is great for deck fittings,
hinges and the like. It has a low coefficient of friction and is long
wearing. It comes in leaded and unleaded versions.Brass tends to be a bit
more brittle. It's tough to tell what kind of bronze/brass you are buying in
premade fittings, the package just says "brass" or "bronze". If you have
specific questions I'll be more than happy to help you out. Softer metals
tend to wear less than harder metals when they rub against each other.
Stainless is terrible for hinges and close tolerance sliding parts.

Oh S#*T. That's going to make a hell of a mess in the boat yard.
Any other suggestions?

Brass is terrible for anything on a boat. The zinc electrolyzes ouot
of it, leaving huge corrosion stains and the materiel turns pink &
brittle. Not that there's anything wrong with turning pink, but
brittle is not nice.

Are you sure? I thought it all has lead in it.

SS is terrible for machine parts, yes. For hinges, doesn't matter so
much. They only get a very little friction and no danger of galling.
The worst thing about SS hinges is that they have a tendency to lock
up from electrolysis against other metals.

Leaded, also known as C485 or C48500 excellent stuff for machining, I
think the lead acts as lubricant and stops your cutter from galling and
sticking. Also terrible stuff to weld and braze, solders ok though. Also
used for bearings. Lead content 1.3-2.2%

Unleaded, AKA C464, C46400, CZ112, or CZ113, doesnt machine well, but is
great for welding and brazing and forging. Max lead content is about
0.2%.
