Aluminum Brazing Technology. For brazing the base material itself without melting, it must use an alloy that has a lower melting point than the base material to be brazed. Though the melting point of aluminum (A1050) is about 650 °C, the brazing filler metal is also based on aluminum, so …

Clamp up the tubing and start heating the aluminum with a propane torch. Aluminum will start to melt at 1200deg Fahrenheit but the brazing rod will melt at around 700deg so we want to get the aluminum hot enough to melt the rod without melting the tubing. Getting the tubing hot enough may take 4 to 5 minutes.
