Kester 24-6040-0053 Solder Roll, 66 Core Size, 0.050 Diameter

Its rosin core 60/40 solder. it melts, sticks to wires and goes solid again and there is enough here to cover my needs for the next decade or so. What more can you ask of solder.

Good Product, Right Price and prompt delivery.

Very good, quality solder. Consistently reliable. If you find a better quality solder, let me know, I dont think there is one.

The best thickness for 95% of the work. I am an engineer, certified for soldered connection on maned space flight. By this solder.

This product works perfect! I enjoy soldering. I will no longer buy cheap crap, which crumbles and eats the tip of the soldering iron.

great product!

Its good stuff. If you need it, buy it!

Runs great and seems quality. Better than the amazon choice.

I prefer the 0.050 size for a multitude of model railroad soldering tasks. It has bee hard to find. Glad to find a source, although it will be some time before I have to reorder.

This is the industry standard for electronics. It wets easily and make an extremely strong chemical bond. I make microphone and instrument cables and the .050 size is the perfect size. Note its a bit easier use if to pull some off the 1lb spool - until you use about of third of it.
