I recall reading about using silver solder but that seems to be more for brass tubing. Thoughts? Cheers, Rob.

Bond seems as strong as solder-copper. For mechanical strength, silver solder and (mini-) torch would be superior.

I use silver solder occasionally to join narrow pieces, where strength is needed. Such as brass-plated eyeglass frames.

Click to expand... I remember Murphy's law: don't force it, use a bigger hammer. If the wire is also brass, and the plate is relatively thin, you can use a regular solder and a regular soldering iron. If the surfaces are not shining clean, use a sandpaper to prepare the surface. You can also use some more aggressive flux (ZnCl2 based). For hard solder, you need a torch. The mechanical strength also depends on the contact area covered with solder. Both leaded and unleaded solder should work fine.
