Silver solder like a Pro!
This flux worked absolutely perfect for an HVAC silver soldering job that I recently did to help my father. You only need a small amount of flux and as soon as it melts and turns clear touch your solder to the fluxed area and it gets sucked into the seam like magic. This is a lot of solder and should last for many years worth of soldering jobs. Highly recommended for professionals and amateurs like myself!

NOT FOR ALUMINUM BRAZING!
Nowhere in the description does it say it shouldn't be used for brazing aluminum. However upon using it with aluminum, it made a huge unrecoverable mess of things. Sure enough, in the Q&A section of the amazon page, somebody asked that and everybody said "No". You'd think "brazing flux" would work for brazing anything you would normally braze, but no. The exceptions really should be listed.

I'm sure it's a great product !
I couldn't use this Flux because because I didn't get the "steel" 1inch by 1/16th square tubing I ordered and got aluminum tubing instead.
