It works
Super easy. Wish I had a small torch for it. Melt it and it sticks. Fixed a radiator with it.

Works well with aluminum evaporator coils
My evaporator coil on my 3-ton air handler unit had a pin hole leak. The leak was on one of the 6 distribution tubes are the expansion device. I had given another "aluminum braze rod" from Home Depot a try, but it failed to seal the leak. I decided to give Aluma braze a try and I was very impressed. I used a propane torch to gentle heat up the aluminum tube and the braze went on like glue. I was very impressed with it. Would highly recommend to anyone trying to fix aluminum coils.

Works on old AC lines
As part of a retrofit job, I used this brazing rod to add a #10 nut to a used and very old R12 automotive AC line. I'm not sure if brazing rod was the best choice but I decided on it because I know it's a stronger bond compared to the lower temp aluminum soldering rods. Plus this rod has a flux core which seems to be very important for capillary action. I would have just tig welded it but I read that tig welding old R12 lines is problematic and results in having pin holes. Not sure if that's true but I didn't want to chance it. Some areas of the joint look a bit bumpy/porous, not sure if that's normal since this is the first time I've done this. I pressure tested it and found no leaks. I'm not able to test it at operating pressure since this is the high side line but I expect it'll be fine. I'll do an update once I get the system operating.

A/C line repair
Worked fantastic. It took quite a bit more heat than expected ,but once it was hot enough the brakes sweet in like I was brazing copper

Es muy buena..pero hay que tener mucha practica en esto .no es tan fácil como se miran en los vídeos..calientas de mas y derrites el aluminio..me lleve poco mas de medio rollo intentando encontrar bien el punto para soldar ..pero que sirve sirve y muy bien...la utilicé en un evaporador de nevera y. Luego presurize con 400 psi de nitrogeno ..no se quebro ni fisura ni nada como otras varillas que si le pones poco mas de 100 PSI la soldadura se revienta... muy buena varilla ..vere si adquiero otra pronto

Une correctamente el cobre con el aluminio no se batalla al soldar como con otras soldaduras
