RE: silicon bronze

SD--- In addition to the good advice Rick has given you, another factor is that stainless and silicone bronze are fairly close to each other on the galvanic chart. The farther apart two metals are on the chart the greater the likelihood of electrolysis and corrosion. You wouldn't want to put stainless fasteners in aluminum assemblies, for example, particularly in an environment where they can get wet. Which is why stainless fasteners are never used on floatplanes, for example.

When we installed some additional bronze cleats on the fore and aft decks of our GB I was able to find bronze fasteners the right size to use for this. However the shipwright we used for various projects back then said that if we hadn't been able to find bronze fasteners stainless fasteners would have been the next best choice because of the proximity of stainless to bronze on the chart.
