In my case the 1930s Muncie aluminum tank had a thin threaded brass neck for the cap. I left the cap on it while the tank soaked several days. At the end I couldnt get the cap off. I then used a strap wrench and the brass ring broke off and remained in the cap. If my chemistry is right brass is composed mainly of copper and zinc.
I used household ammonia full strength.
The brass necks on the 30s omc tanks are much thicker and they never gave me a problem.
