Your cart is empty.The Forney 48571 Super Sil-Flo brazing rod is a brazing alloy that is ideal for large and small copper tubing installations. Self-fluxing on copper. Typical applications include refrigeration control valves (copper and brass), joining copper wires to rotor bars, electrical connections, radiant heating systems, air conditioning units, hot and cold water lines and heat exchanges. T-joints, swage joints and sleeves, couplings on return bends and condenser fittings. Sil-Flo is not recommended for ferrous metals such as iron or steel. It is only for copper base metals as an effective economical alternative to copper-silver alloy rods.

It works fine and costs a fraction of what sil-fos does. Very strong joint on copper-copper or copper-brass. Can be layered over a fluxed brazing rod to touch up a copper-steel joint, but won't stick to bare steel at all.Melts fine with oxy-propane, so not sure why someone complained about performance with oxy-MAPP? You definitely need oxy-fuel though.I have to dock a star for the naming. Don't call it "SIL" when there's no silver. You can still market it as a sil-fos replacement without trying to fool people.

Bought these rods to braze and HVAC lines when I replaced my air conditioning unit in my home. These work perfectly had the right compound so that the material flowed nicely.

I've used silver brazing rods for 40+ years. I bought these because they are much less expensive than silver. I tried them out and as far as I can tell they work just like silver rods. I think they might have a slightly lower melting point, which is fine with me. I like to go outside and work on my Ham Radio wire antennas. I use a Mapp gas torch for this. With the silver rods, it took a little more effort to melt then. These flow perfectly. The joint formed is hard as rock.

I'm just learning how to braze in jewelry making. This was my first purchase. recommended from a professional metalsmither. Before using I cut them in thirds and ran them thru my rolling mill tight enough so they split. I learned that doing more than 1/3 they wouldn't split. By splitting you have less solder to go onto the metal and that's a good thing. Otherwise these are too thick for this process. When I run out I plan on buying more of the same.

I would like to tell you that I used this and love it, but by the time I found this, ordered it, and finally received it, I was done with my particular job. What I see here is a perfect looking replacement for the 10-15% silver content rod that we all pay thorugh the nose for normally. Forney promises that this will do just as well...... my best guess based upon previous Forney products used is that it will be equal, or very likely,.... a bit better than the expensive stuff. However that may be, I do NOT know that for sure yet. I do not need it it right now, and have no jobs in the immediate future to do so. Later on, if I find it is a lot better, I will find and update this posting. I do hope it helps someone out there who is fearful of it failing. As I said, the Forney name is why I bought it, and based upon my history with Forney, this is good stuff and will save you a LOT of hard earned money to do the same job just as well! Enjoy.
