Aluminum Brazing Rods

I have used the HTS-2000 brazing rods from here: https://www.aluminumrepair.com/

They work with a standard acetylene gas rig.

You need to get the aluminum very clean, as it oxides very quickly when heated. Aluminum also melts at a lower temperature then steel and dissipates the heat from the heated area very rapidly. Where steel changes color when it is time to add filler, aluminum just melts, so the process requires some practice.

Welding aluminum with a gas rig requires the correct flux and filler rod. Requires a lot of practice and is not as forgiving as welding steel.
