I have found some info on the web, and suggest you search for
"solder" and "strength".
For example:
Type Sn63 Silver-bearing
(no % listed)
Yield Strength (ksi) 4.38 4.86
A little better, but not a whole lot.
KappTec claims to be almost as strong as silver solder, but flows at
a much lower temp. Beware, though, as it's 95% Cadmium, the
vapor from which will go straight to your testicles and do things you
don't want done to them.
I didn't find a yield strength for silver solder (or silver brazing, as it's
also correctly known) but I'm sure there's one out there somewhere.
