4104 4004 brazing filler metal

The Introduction of 4104 4004 brazing filler metal
Al-Si-Mg ternary brazing filler metals, Mg is added on the basis of Al-Si brazing filler metals. The addition of Mg enables the brazing filler metals to generate Mg vapor during the brazing process, thereby absorbing the water vapor in the furnace body. Secondly, the existence of a stable oxide film (Al203) on the surface of the aluminum alloy hinders the wetting of the base metal and the solder. Simply relying on vacuum cannot effectively remove the oxide film, and Mg can just act as an activator to remove the oxide. The role of the film makes the solder well wet the base metal. 4104 4004 brazing filler metal is a common AI-Si-Mg series solder.
