Richard, Whilst I do not have any technical data, I do know from experience in the marine environment that unprotected aluminium does corrode severely when in contact with stainless steel. Over 5 to 10 years the aluminium could be severely corroded.
The salt water obviously speeds the process. In dry conditions, there would be very little corrosion.
