Not sure if the second part of your comment is still referring to my post, but in case others take it that way:
All three materials mentioned are about as good as it gets with regard to
corrosion in salt laden atmosphere or salt spray.
Titanium has such a low rate (as Stumble will be well aware) that it is not practicable to measure it
Beryllium copper is another wonder material : self antifouling like cupronickels, strong and hard enough to be usable as a spring material, extensively used for difficult bushing applications such as aircraft landing
gear. It is used - and after thirty years remains virtually like new- for the housings for sea-floor
cables.
And Ampco produce aluminium
bronze grades (also nickel aluminium bronze, the mere mention of which makes mechanical engineers smile and relax) with particularly high performance, which is saying something, because even common grades of aluminium bronze are remarkable materials.
