    Don't know if the flux would be an issue, but this stuff has been around for awhile and can be a lifesaver at times..
    You are the second person to mention Muggyweld so I guess it must be worth a try. I will have to see about getting some. I always like having as many options as possible in metal working and fastening.

      Online descriptions of this aluminum brazing rod says it contains flux. How do you know it isn't corrosive to the copper?

            It's plain metal alloy, no flux at all.

              I have a roll of Aluminum solder at work. I think it has some silver in the alloy and the flux is quite aggressive.

              It works very well for electrical/electronic work, but its mechanical strength isn't that good.

              I mostly use it for making connections to PT100 temperature sensors. The wires on these seem to be Nickle plated Iron and can be very reluctant to wet with conventional solder. Once wetted with the Aluminium solder, I wipe them off and use the ordinary stuff.
