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

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 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.

Nothing does - but for everyday soldering I'm just happy this is available and works just like it did in the old days. Tin/Lead solder was developed because it WORKS. No silly green concerns - a reliable, simple electrical connection has more merits than some might think. It was fresh solder, and the flux was more than adequate for 12vdc wiring that I needed to do. Good stuff.

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.

This is a large-gauge solder, so not ideal for the small components I usually solder. This would probably be more useful for a soldering gun than an iron. But, I've found this solder works extremely well for flushing the iron tip. I'm not sure if the flux is somewhat more aggressive than other brands, but it cleans and removes oxidation very reliably. Even more so than the "tip-refresher" products on the market. It's my go-to for keeping the tip wet during non-use.

I'm a first timer on soldering but this was a reasonable price for what appears to be a good product. I've used it several times now and have had no problems with it. Everything I have soldered has gone well and worked. What more can you want. I went with this as it is a lead product and I read that lead was easier to work with than the lead free products. I hadn't used either previously so I don't know if that's true or not but I do know it works.

Best solder I've used yet tried multiple different solders and this one takes the win for electronic soldering.

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

the product was good except the lack of of detailed descriptions there are no information about the product specifications except the image which is accurate by the way but that's all. so after receiving it I find out the diameter of the wire is about 1 mm which is too big for my electronic application

La hubiera preferido de 0.031" pero sabiendo aplicarla el tiempo necesario no hace falta que sea más delgada. Me gusta: El acabado que deja. Cantidad suficiente de flux interno. No tiene olor desagradable (aunque utilices extractor de humo el olor se alcanza a percibir, como cualquier soldadura) No me gusta: El grosor 0.062", aún así no dudaría en recomendarla al 100%.

Buen producto

Hace lo qu tiene que hacer. El producto coresponde a la descripcion. Es perfecto para hacer soldaduras muy chiquas, en microcomponentes

Es un poquito gruesa, de lo demás hace muy bien el trabajo, con una punta de cautín fina haces maravillas con esta soldadura, huele rico! a soldadura de calidad =D
