Hot Max 24184 Aluminum Brazing Flux for Welding

I had to go to the how to internet, to find how to use this product. I still think i'm doing something wrong. Trying to contact the seller, was redirected to a sight with no reference to this product. I'm sure this product works great, it will work better with some instruction.

I am not sure how to rate it. It seemed to work ok. I still had issues with the brazing job I was doing, but I don't know if the issue was the flux or not.

Works great on soldering

Didn’t figure out how to use it. My teenage son is inexperienced with welding.

Warm the aluminum brazing rod well and dip, and this flux works just about the same as flux that goes with brass or steel rod. I am pleased with the way it works, and the results, although aluminum varies a lot in its alloys, and flow characteristics vary as well. On some things, the aluminum brazing was easy, and on other things it has been more of a challenge, but either way, this flux does help.

This stuff made a huge difference when brazing aluminum with brazing rods. Be sure to thoroughly heat your base metal, use MAP gas rather than propane, and be patient. Brazing with MAP gas isn’t easy but it works for small repairs if you don’t have a TIG welder.

when you put if over a clean piece of aluminum.. (brushed) and you heat it until it gets liquid... it doesnt flow into all the aluminum as it should... it kind of just stays in one place... if you then put the aluminum rod on that.. it beads off like water.. if you just use the rods with no flux.. they stick just fine.... they just dont flow into the holes like things with flux.. You cant return this since is a hazardous material.. so there... buy.. fail and keep it. May as well include a free kick in the balls with purchase..
