Alpha Fry AT-31604 60-40 Rosin Core Solder (4 Ounces)

This solder is exactly as described as far as I can tell. I am a (relative) novice in soldering but everything looks fine. I actually meant to order the thinner stuff but that's not the seller's fault. I just forgot to check. This size will work. This is easily the best solder I've ever used. Granted, I have only bought solder 2-3 times in the past and that was years ago. The last time was lead free solder. I did not realize it was inferior because I was only thinking about the fact that I wanted solder without lead and didn't know any better.I have a new iron on order but the solder arrived before the iron so I tried this out with my OLD iron (easily over ten years old). It's just a cheap 30 watt Radio Shack iron with a horribly ruined tip (I have only recently been doing research on how to solder). Once it got up to temp, this solder seemed to flow and stick to 18 gauge stranded copper wire just fine and made a strong joint.My new iron was also cheap and will be a 30 watt but (assuming it actually works) I'm sure this solder will be fine for it. No more often than I actually need to solder anything, this roll will probably last for years. It's just the kind of thing you need in your toolbox even if you don't use it all the time.Anyway, never heard of this brand but it seems perfectly fine if you need this size.

works good when solding.

I have a year old Weller WLC100 40-Watt Soldering Station. I'd been using some solder from Harbor Freight Tools, but I always had trouble tinning my tip. Eventually, it got to the point where solder just rolled off the tip, and it was nearly impossible to transfer heat to make a solder joint. I new it most likely wasn't the soldering iron, and I was afraid I some how had destroyed three different soldering tips through my inexperience. But then I ordered this solder, and right away, it started cleaning off my tip, and I had no trouble at all tinning my tip. Now soldering is a breeze. I can solder an audio connector in a matter of seconds, not the 5-15 minutes it was taking before. So my message is twofold: This solder works very well for both small electronics and larger wires for audio cables (it's thick enough for audio cables, but not ridiculously thick to use on electrical components, like LEDs. And the solder they sell in coils at Harbor Freight Tools is absolute junk. If you're having trouble soldering, try this solder first, before buying a new tip or throwing out your iron, or trying to drip solder on your connections.

It's a good solder and It flows nicely. However, there's no way this is 0.062" in diameter. At least, not the roll i got. It's way too thick for pcb work.

I've soldered off and on for about 10 yrs. Like most I started with generic equipment and was able to solder small wires 30-18 gauge for small electronics and LEDs. Several years ago I got into electric RC cars, boats and helicopters and needed to solder thicker, 12 gauge wires and that's when I bought a Hakko 936 soldering station since its supposed to be one of the better ones under $100, yet I had some issues with 10 gauge wires until now!!Received the solder today and I was skeptical since I normally use .032 solder and this is twice as thick. I started with 24 gauge wire and was not impressed. However that changed once I moved to thicker wires. 12 and 10 gauge are a breeze to solder even 8 gauge is easy. Then I switched back to my other solder spools (wasn't sure if I was using better solder or if my skills had improved since I last attempted to solder 8 gauge wire, nope skill is about the same. I'm just using better quality solder).I'm ordering another spool and redoing all my RC vehicles, LiPO batteries and car audio

Used this to Solder some new 6 volt old car battery cable ends. Perfect product for the job and used with “SRA Rosin Paste Flux #135 in a 2 oz Jar” from Amazon too.Only thing I’d like differently is for the thickness to be twice the size, but that’s not their fault I just couldn’t find that size for my application. For the application I was using it for, it still worked great but had to unroll a few feet a couple times to have enough to solder the 2/0 cable ends & cable together. For fine electrical applications such as 16 gauge wire, it would be the perfect size.3/1/19 update: working perfectly for me Electrical application! I covered the soldered joints with some electrical shrink wrap to keep it from corroding.

I do my share of soldering, and usually I have to provide extra flux and get it super clean, and do a little extra prep work and apply a little more heat than I'd like, Not with this solder.This solder is exceptional, it flows well, and adheres well, even on poorly prepped surfaces.Well made, and well thought out, it made the job easier than expected.

If you're a mild-moderate user & debating between the thinner & thicker wire, I would choose the thinner. It is very easy/convenient to pull off ~6' of thinner wire, fold it in half, fasten one end to a stationary object, stick the other end in a drill, and spin the drill to make a double thickness wire. Then I have ~3' of thicker wire that I wrap into a nice bundle & keep in my soldering iron kit.Seems to be really good stuff. I'm no electrician, but know the importance of having quality tools (especially when you lack the talent/technique/knowledge to work around the faults of poor quality). This is definitely easier to use than the typical thick stuff you would find packaged with a new soldering iron, or get in those small tubes. My local electronics supply warehouse agreed that it was a quality product, I trust their knowledge a lot more than mine.
