I want to try soldering some aluminum plate (0.032”) onto each side
of
a brass cylinder. When trying to solder aluminum in the past I
failed. I think I heard that some Al alloys are easier to solder
than
others. I’ve got a choice (From McMaster-C) of 6061, 2024. 7075, and
1100. Any idea of which is better?

I was also planning on getting some aluminum flux and some Zn/tin
solder from McM-C. Other suggestions welcome.


Thanks
