Alumin spars etc are generally anodised for marine use.
Even so bad corrosion problems can occur, especially where salt lodges under
fittings and it all explodes with white crud.
Stainless rigging does break, typically at end fittings, and masts fall
down, failure of masts often attributed to vibration rather than load
Old timers still speak well of galvanised wire and fittings for marine use.
