Need or Galvanic Series Potential in Flowing Sea Water.

[WKTaylor]

Folks...

I need to know the "galvanic Series" potential in "flowing sea-water" for Titanium-Columbium alloy AMS4982 [Ti-45Cb] used mostly in aerospace fasteners...although I believe a form of this alloy is also a "super-conductor" wire at VL-Temps.

Mil-Std-889 and Mil-Hdbk-729 Are not very helpful... and even the vendor for the alloy has been "vague" at best, lumping it in with titaniums and noble metals.

My concern is the use of this alloy riveted-thru aluminum aerospace alloys 2XXX and 7XXX in high strength joint applications. Any info on this alloy, that can be verified by other M&P pros, would be useful. NOTE: this material is used for high strength driven rivets [NAS1097, MS20426 and MS20470]. Properties "as is" [un-driven] appreciated... although "driven" [cold-formed] would be "ideal".

Heck I'd settle for Density at this point ... 'course Young's Modulus, Poisson's Ratio, Yield Strength, Ultimate Tensile Strength and Thermal Conductivity wouldn't be bad either ... sure help get this Family Part/iPart table fleshed out today maybe. Anyone knows and wouldn't and mind post'n it I be grateful. Thanks!
