## Customer Reviews

### ⭐⭐⭐⭐⭐ I suck
*by B***R on December 9, 2023*

Aluminum is a pain. Tring to weld with substandard tools. This had the best ratings. I am not good enough to tell you about it. But I trust seller and company and that's sometimes all the help we need

### ⭐ utter garbage.
*by S***L on May 25, 2025*

This is garbage, avoid. Others have noted (and boy do I wish I saw before buying) you can literally melt out the aluminum under it without it wetting.I literally had better luck brazing with a freshly cleaned metal surface than with this added.

### ⭐⭐⭐ Learning how to braze aluminum
*by D***W on March 24, 2025*

This was purchased as an experiment to see if I could improve the 'wetting' of my aluminum brazing rod. I had mixed results bonding aluminum to aluminum with that generic aluminum brazing rod (reviewed elsewhere) and so I thought I'd try this flux. It works best when mixed with water and applied as a paste per the instructions; the flame of the torch just blows away the white powder. Once I could apply this flux to the work area, I could not tell any difference in the quality of my brazing joints. I will not fault the flux, as my experience, working temperature, and working material were all variables in my results. It was a good experiment but didn't improve my work. YMMV.
