So, there must be more to galvanic corrosion than just where various 
elements sit on the potential chart. For example, I recently purchased 
an electrical junction box to mount on the tower with some relays in 
it. In the box was a ground lug, made of some shiny metal, and it was 
labelled for use with copper or aluminum wire. Don't know what this 
ground lug was composed of.
Any metallurgists, chemists or others with the facts that can educate 
us on the use of dissimilar metals?
