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.

Works great on soldering

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.

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.

Works great... I tried making joints with and without. The joints made with the flux look great the Braze alloy flows evenly; joints without flux bead up and do not flow. Note that it is a powder and will not stick to vertical surfaces.Also it is hygroscopic (absorbs water). Letting the flux sit in a humid environment makes it easy to clean off (after brazing). Until then it is rock hard after braze.
