Silicon Bronze Rigging Fittings

[Storm]

I am in the process of fabricating silicon bronze chain plates to replace my exitsing 316 SS that are showing signs of crevice corrosion and stress corrosion cracking. I am also thinking maybe I should use silicon bronze to replace some of the mast tangs and other bits of 316 SS that currently make up my standing rigging. Do you see any problems with this? Would the bronze in contact with the aluminum mast be a significant corrosion issue?

Putting bronze hardware on a aluminum mast will require a structural galvonic isolater or it will make metal jelly soup and give you no benifit over SS other than being able to say that you have bronze tangs on your mast. Bronze makes sense if you can afford it for chain plates, kranze and gammon irons, bobstay and boomkin stay tangs cleats and misc deck harware. If you have a wood mast then yes all bronze all the way up.

It is improtant to note that all purists will go on and on about the evils of SS and how everything should be bronze because it will last 1000 years etc, however it is a working piece of rigging and however better suited to the SW elements than SS it will still wear out get fatigued need to be inspectd just as much as the same piece in SS.
