20 Sticks Aluminum Brazing Rods 1/16",14" Length Aluminum Welding Rods for Ppropane Torch，Low Temperature 550℃/1022℉ Welding Wire with Flux Core for Aluminum Repair

These work very good for HVAC Work.

They serve their purpose perfectly

These don’t work. I tried 2 sticks and they require excessive heat to the point of where the base metal was damaged. Get the Hobart brand brazing rods. They actually work.

Went on smoothly

Worked as intended

Package contains 10 sticks, total weight is 4oz, no specs or marking except raised letters on the sticks saying CHINA and OIXING. I was intrigued if a regular handheld propane torch/tank could achieve enough heat to braze copper with these. I found a 4” stub of 1/2” Type L copper with a brass ferrule from a compression fitting on it, seemed like a perfect candidate. The torch had no problem heating the ferrule, in fact it could get it red hot easily. Heating the copper tubing was much slower, but after a minute it got hot enough for the brazing rod to start to flow. As I said this is a stub of copper held at one end in a vise, so it was pretty well isolated. I think it would be a struggle to heat tube that was located near a large fitting, but you could do small hobby and craft stuff with a propane torch. Then I switched over to a TIG torch, set to 100a max. With this it was easy to heat the copper tube and the brazing rod flowed well.

Tried with 3 different alloys of aluminum by heating them up and trying to melt the rod on the hot aluminum. In each case the aluminum melted long before the rod started to melt. I Even placed a piece of this rod on melted aluminum soup and it just layed there like a piece of *** in toilet - pretty much says it all what there is to be said
