Uniweld is the best
Great for radiators

Copper to Aluminum. Easy flow. Great joints.
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.

Good repair solder
I have tried aluminum solder before to no avail. This solder works as good as using other solders as far as flowing out on the prices to be repaired and is very strong.

Worked as advertised.

Easy to use
Self fluxing, nice flow characteristics

Clean both tubes. Use brush or sandpaper.
Clean both tubes, one outside and one inside, use minimum temperature so as not to melt the aluminum tube, works great.

Worked great for installing our air to air minisplits
During our mini split installation, we had to solder copper tubing to aluminum. It seems pricey, but it was worth its weight in gold compared to paying for soneone else to complete the installation. This stuff flows out easily if you follow the instructions carefully.

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.
