Steel + ali results in much accelerated corrosion of the ali. Not a
good combination

Brass,steel, ali is worse:-)

we can only guess what that means.

I once used pop rivets (aluminium) to secure protective strips to a
sports car wing. The real mistake was using brass washers under the
rivet heads. Moist road salt environment, they lasted less than 12
months.

Someone will chip in with the electrical activity numbers for various
metals:-)

So what would you use for an ali door? Casting ali hinges & using ali rivets might be ideal but it's a bit of a faff.
