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

rivet heads. Moist road salt environment, they lasted less than 12
months.

Someone will chip in with the electrical activity numbers for various
