This is a wonderful solder to use when connecting two flat pieces or pieces that will not have any stresses, like bending, on the joins after the project is completed. All metal manipulation must be completed before soldering.
I tried using this on bangles I was hammer texturing and every seam failed while texturing. It took a lot of research at that time, but I found that this particular solder is too brittle to handle texturing.
Just like other solders used on copper, this is not a color match, even though the coil is copper colored. The solder seam will be silvery colored. All the pieces I have used this solder on have accepted a nice patina, disguising the join. These three pieces were constructed using copper wire solder. Even with no patina to cover the joins of the pieces in the third photo, this solder still looks good.
