According to the SDS (MSDS) it is methylene chloride, methanol, and mineral spirits. I would not worry about inherent corrosion due to the ingredients.
Some paint removers do use caustic chemicals that react badly with aluminum, these don't.
I have never stripped an aircraft, but remember a PBS program that demonstrated use of denatured alcohol, and buckets of wood shavings (like from a planer). They lathered on the remover, waited, scraped, then immediately washed (before totally dry) with a brush and denatured alcohol, and while still wet . . . piled on the shavings & dust to soak all up and scrubbed around to leave the surface amazingly clean. The dust soaked/dryed and the shavings became a scraper, the initial alcohol kept the removed material soft. Last was an alcohol wipe with cheese cloth for final surface clean. This process has worked well for my furniture adventures. Use heavy rubber gloves and respirator for the methylene chloride vapors.
