Greetings all -

How do you braze or solder a brass fitting to an aluminum manifold?
Thanks, Willer

A tin-zinc solder or pure tin would probably work with the right flux,
some better than others of course. Tin silver solder (as Harris Staybrite)
might work with the right flux. Harris Staykleen is not the right flux
here, don't know what might be.

Some will say that lead-tin solder works if the al is scrubbed while
soldering. I've never had what I considered satisfactory results from this,
YMMV.

I would try Aero Solder and flux from

It works very well for al-to-al and/or al-to-copper, so I'd expect it to
join al to brass as well but I've never tried it. If you're not in a
hurry, I'll try it with brass when I return later next week and let you know
how it works.
