I've heard this is stronger than regular solder.

However, I'm getting conflicting reports that one needs a hotter soldering iron or no, you can use a regular one. (I use a 35 watt iron.)

I'm assuming that silver solder is more expensive and this is not the solder that Fast-Tracks sells?

Can one get it in a small enough diameter?

Thanks in advance

There is a difference between silver solder and silver bearing solder. Both will need more heat than lead-tin solder, but the silver bearing solder is still accomplished with an iron. There are some silver bearing solders that are in a paste form, and these can be very convenient. True silver solder will require flame torch heat and is more closely associated with brazing than soldering.

The 96% tin and 4% silver solder from H&N is solid wire, 1/32" (.79mm) diameter, requires a flux (the H&N "Super Safe" liquid flux is recommended), melts at 460 deg. F (237 deg. C), strong - 5 times more than 60/40 lead/tin solder, and great for RR Track work.

Note the H&N 60/40 lead/tin solder is solid wire, 1/32" (.79mm) diameter, requires a flux (again - use Super Safe liquid flux), melts at 430 deg. F (221 deg. C), and is often the normal solder and is preferred for for electrical work.

The Super Safe liquid flux is organic, water soluble, no resins or strong acids, active 390 - 520 deg. F (198 - 271deg. C), cleans up with hot water, solders Brass, Copper, Nickel, Tin, some Steel, and excellent for all electronics. (This is not liquid rosin flux, nor acid based - but far superior).

if you want a very good solder try Kester "44" Resin Core Solder
alloy Sn63
Core 58
Dia .31 or .24 if you want tiny super thin solder
part # QQ-S-571
W-RA-P2
this is a Silver/Nickel solder that is perfect for the Micro Engineering Rail as well
as the copper PC Ties. It requires a very thin layer of solder for a very strong and
permanent weld and a 25-35 watt Iron works with great results.
