Re: Aluminum brazing

[rudderless]

The issue is the melting point of the base material is very close to the melting point of the filler material. Usually one needs to lay flat the work and puddle or float the filler around the work using steel strips to make a dam. A friend was trying to save an IO gear case using that stuff. As he was heating the work the work melted at the same temp as the al rod. Ended up with a puddle of rod and a section of gear case on the bench all liquidized…was the TV stuff..
