Uniweld UAB Aluma-Braze™, All In-One Flux Cored Aluminum Brazing Alloy

I used this Brazing Alloy to repair a refrigerator that had a pinhole leak where the copper piping met the aluminum coil. I had my doubts on if this would work as brazing copper to aluminum is difficult and prone to leaks which is why my fridge leaked in the first place. The refrigerator company saved .2 cents by using aluminum tubing and told me my fridge was junk after only 3 years and not reparable. Instead of throwing it into the land fill i gave this brazing wire a try and what do you know it fixed the leak. It wasn't very difficult to use just a little pricey. However it saved a refrigerator from the landfill so i would say it was worth every penny.

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

Good value for the price I didn’t end up using it and returned it

Works well and is easy to use.

This stuff works amazing. I can't believe how easily the flow started. The bond was strong as anything, no leaks. Copper to aluminum. Just spend your time cleaning the joint, especially the surfaces to mate. This is a low-temp brazing solder, too. So you can literally use a butane torch or a 60-watt soldering iron to get this to flow. I'm not saying that will get your joint hot enough, but this is a low-temp solder. Flows easy. Durable joints the very first time. Couldn't have asked for more.
