Conductivity for a hunk of metal 62 mils thick by quarter inch wide by a
foot long where you measure resistance in the micro-ohms means absolutely
nothing -- copper, brass, or aluminum. On the other hand, corrosion means
a lot -- like steel hardware on aluminum, no matter how good the plating
on the steel.

All good points. So, what is it that you are trying to say , in regards to
which material should be used, and which to stay away from?
