An Excerpt from the Tech. Article - Copper & Nickel Alloys:
"Keel bolts, for lead keels on fiberglass or wooden hulls, shouldn't be of stainless. Such bolts are (as we saw last issue) in exactly the worst environment for stainless underwater-in stagnant water (when any water gets in and it will). I once had a young engineer at a major keel manufacturer solemnly explain that bronze wasn't strong enough for keel bolts?! I managed not to laugh. Not only does bronze have nearly the same tensile strength as stainless, but bronze's corrosion resistance is infinitely superior in this application. Bronze keel bolts are the standard and have been for over 150 years.
The best known silicon bronze is probably Everdur, a trademark bronze generally of 95% or higher copper, with about 3% silicon, and 1% manganese. Silicon bronze (Everdur) is about my all-around favorite marine metal. The top pick for most marine screws and bolts, it has a tensile strength of 90,000 psi in hard temper, and 55,000 psi in soft temper. It'll never corrode (unless you're foolish enough to fasten it directly to steel or aluminum, where it will cause corrosion in the aluminum or steel). It can be cast, welded, rolled, bent and otherwise formed without harm."
