To All,
Here is a list I found very interesting
Some one on the board had suggested placing a sacrificial anode in the cell, to protect the working metals, I thought that was a good idea
************************************************** ****
This is a list of metals in order from most to least reactive in sea water. If there are two metals near each other in salt water, the one which is the more reacive (a.k.a. "least noble") will corrode, thus protecting the other metal. This is why ships often put chunks of zinc (called "zinc lozenges") near the propeller---without the zinc, the steel hull would corrode very quickly as it is more reactive than the bronze propeller. The zinc is more reactive than steel even, so it will do all the corroding and the hull is protected. Of course you have to replace your zinc lozenges periodically, as they will corrode away to nothingness eventually.
From Most Noble (Protected Metals) to Least Noble (Corroded Metals):
Mercury
Vanadium
Gold
Silver
Monel
Nickel
Passivated Stainless Steel (rare type)
Copper
Brass
Tin
Lead
Active Stainless Steel (most common type)
Cast Iron
Steel
Aluminum
Zinc
Magnesium

Best of luck to all
