Here's a text version of Nick's Galvanic chart. This is specific to salt water applications, too!
Galvanic Series in Seawater A galvanic series has been drawn up for metals and alloys in seawater, which shows their relative nobility. The series is based on corrosion potential measurements in seawater. The relative position of the materials can change in other environments. The further apart the materials are in this series, the higher the risk of galvanic corrosion. Note: There's a big difference between plain and passivated stainless.... Me, I'm just going to build my next boat exclusively out of Platinum, Gold, Graphite and Titanium!!! Most cathodic, noble, or resistant to corrosion Platinum Gold Graphite Titanium Silver Chlorimet 3 Hastelloy C 18-8 Mo stainless steel (passive) 18-8 stainless steel (passive) Chromium steel >11 % Cr (passive) Inconel (passive) Nickel (passive) Silver solder Monel Bronzes Copper Brasses Chlorimet 2 Hastelloy B Inconel (active) Nickel (active) Tin Lead Lead-tin solders 18-8 Mo stainless steel (active) 18-8 stainless steel (active) Ni-resist Chromium steel >11 % Cr (active) Cast iron Steel or iron 2024 aluminum Cadmium Commercially pure aluminium Zinc Magnesium and its alloys Most anodic or easy to corrode |

Good Luck !!! I have "seized" stainless and aluminum together and NEVER got it apart !!!! Time for the torches / saws all and new parts. Sorry, Dave

My Way !
I Still think my BAJABOB 38 idea is the best,cheapest,and fastest method.:evilb::evilb:
