  63/37 eutectic has a 1 degree plastic range. Been using it for a
couple
  decades now commercially and hobby wise.

Just to pick up a couple of loose ends:

The 63/3 means 63% tin, 37% lead and is the metal alloy of the solder.
That's the same manufacturer to manufacturer.

The Kester 44 is the FLUX type. I think it's RMA...  Rosin, Mildly
Activated (or Active). Likely Ersin uses a somewhat different flux.

Finally, the o.o15" OD is a bit thin for BA work. That just means you
will have to feed more length of bthe stuff.

I've been using the Kester 44 for at least 25 years and it works very
nicely. One caution: it may start to get harder to get soon as the EUC
and others have banned lead.
