Only explanation I can come up with is galvanic corrosion caused by ean lectrochemical process where one metal corrodes preferentially to another (dissimilar metal) resulting from both being in electrical contact with an electrolyte ?

I agree - galvanic corrosion. Replacement being aluminum, hopefully resolves this. Hey, look at the bright side, now we know we can service anything, including HVAC unit under the dash. Anyone up for reupholstering the dash in fine Scadinavic leather?
