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?

I took what he was saying to be that the difference in conductivity
between the materials mentioned for the size piece in question isn't a
factor worth worrying about. Compatibility with the connectors is much
more important as any galvanic corrosion between the connector and the
buss bar will cause substantially more resistance than will the
difference in buss bar material.

So pick the buss bar material which is most compatible with your
connector material.
