Here's how one reference describes the advantage of silver:
*60/40 and 63/37 Solders*
These solders are used in the stained glass industry and also for
electronic component such as computers and communications equipment
where a minimum of heat can be used to make the connection. For the
electronics industry, silver is added to tin/lead solders to reduce
the dissolution of silver from silver alloy coatings. Silver may
also be added to improve creep resistance.

You may also recall the old Tektronix vacuum tube oscilloscopes built
with ceramic strips. The notches were metalized with a silver-bearing
compound and the scopes had a short length of silver bearing solder
included with each scope. (I think that might have been 4% silver, but
it's been a long time.)

There's probably a better source for 62/36/2 solder than RS, but it's
decent stuff, unlike a lot of the things one finds there.
What's the advantage of 2% Ag over plain 63/37 Pb/Sn eutectic?
