Brass & bronze mix

[bjornar]

Any of you guys (it seems to be a lack of girls on this forum, but I'm just as happy with an answer from any girls that might be out there) that can tell me how big mistake I'm making if I replace a few of the brass fasteners below the waterline with bronze.
I need to replace a couple of delaminated frames and found that the planking is fastened with brass screws. The condition of these screws are not very good, but I'm not prepared to replace them all. At least not this winter.
I'm however reluctant to replace the brass screws with brass even though all literature recommend to put in the same metal as I remove.
Today, we all know that brass is crap below the waterline. On the other hand; I wouldn't like to see the remaining crap screws totally disappearing just because I fancy bronze.
By the way - The boat is a 35' sloop buildt in 1961.

You will probably get a wide variety of answers on this, but I'm going to go ahead & say that I would do as you are planning. replace with bronze as you go along. As brass is pretty much copper & zinc, and bronze is pretty much copper & tin (ok, there are lots of other things that can be in bronze as well), the biggest issue I would see is that you might hasten along the de-zincification of the remaining brass screws a bit.
