It has less of a tendancy to corrode "oxidize the lead" than does
a standard solder. It is also stronger, but requires more heat.

Silver solder is not silver per se, but rather an alloy of Lead, Tin,
Silver and a little of everything else imaginable. Ive seen different
colors from different vendors, but most seem to have a touch of
red to the color, suggesting a hint of brass. Also, some of the best
silver solder I have bought has a warning that it contains Cadmium,
which you really ought not to inhale.

Silver solder has a harder finish compared to Tin Lead, and I've even
used it on radiators.
