There's a rod for aluminum to aluminum now that works pretty well, but
it won't stick it to any other metal. It's more like brazing than
soldering, but you can do it with propane or MAPP gas.

I have an entire book, published by Alcoa some years ago, about soldering
aluminum. This is ordinary soft solder they were talking about, although
there are some alloys that make it easier.

The idea that you can't use ordinary soft solder on aluminum is a mistake.
It's been done in industry since at least the 1920s.
