Silicon bronze is promoted by the manufacturers because it is easier and cheaper to manufacture fasteners with it. The silicon is there to make machining easier, not to make your application work better or last longer.

Aluminum bronze contains virtually no zinc, especially compared to SiBrz and is a far better material for underwater marine fasteners. For the number of screws you are looking at, contact one of the fastener manufacturers and get a quote for the amount you need.
