Copper would be a dubious option. It might tend to elongate or bend under the load unless the bolts were absolutely huge. (Talk to a metallurgist, but this may be why you don't see many big copper bolts.) I'd also be concerned about the reaction copper might have with salty bilge water. Stainless has its issues, but would probably be better than copper. Another solution, la Fatty Goodlander of CruisingWorld, would be to look online for some silicon bronze bolts of the right size from a reputable manufacturer and have them air shipped to you. Though it might be expensive, it would certainly be less than having the keel fall off somewhere near Sumatra, and a lot less exciting.
