I'm no metallurgist so forgive my ignorance. Most of
us have had the problem of interfacing copper to
aluminum. Is there some sort of alloy terminal block

to create an alloy that gradually transitions from
copper to aluminum but what do I know?

Cecil, there are plenty of connectors ( Bronze? ) on the market that
accept copper/alluminum
combinations. On the other hand I understand that if the joint is free
from the atmosphere
i.e. a tight interface the problem is not all that bad, G.E proved in
court during the 50's that if the connection
is tight or embedded an increase in resistance does not occur, I
believe that analysis still stands.
Co defendants that could not provide a similar defence got hammered
because their joints did
not provide a virgin interface thus existing corrosion was trapped
thus it could grow.to a sizable resistance
