[Fot] Corrosion Cells

[A Daniel Cronin]

Came across the following information in an old book (Rust and Rot) and
thought some on the lists might find it of use........

"there are two parts
to a corrosion cell, the cathode (stays intact) and the anode (corrodes).  In
the list of metals below, the greater the distance apart, the greater the
corrosive forces..."    AL is a special case due to its protective oxidation
coating.

  Carbon  Silver  18/8 Stainless Steel   Monel metal  Bronze  
Brass   Nickel   Tin   Lead   Lead/tin solder   Cast iron      Wrought
steel   Mild steel   Cadmium   Impure Aluminum   Pure AL   Zinc   Magnesium
alloy   Magnesium  

 (Zinc is a good in-between isolator for dis-similar
metals)
