Shenzhen Su's pure aluminum water-cooled plate vacuum brazing
Song Dynasty> The brazing properties of aluminum and aluminum alloys are poor. The main reason is that the oxide film on its surface is difficult to remove. . Aluminum has a great affinity for oxygen and can easily form a dense and stable oxide film with a high melting point on the surface

宋体>. At the same time, aluminum alloys containing magnesium will also form a very stable oxide film. The oxide film

宋体>. They can severely hinder solder wetting and spreading. And it's very difficult to remove. In brazing, the brazing process can only be carried out if a suitable flux is used.
The corrosion resistance of aluminum and aluminum alloy brazed joints is easily affected by filler metal and flux. The electrode potential of aluminum and aluminum alloys is quite different from that of the solder, which reduces the corrosion resistance of the joint, especially the impact on soldered joints is more obvious. In addition, most of the fluxes used in brazing aluminum and aluminum alloys are highly corrosive. Even if they are cleaned after brazing, the impact of the flux on the corrosion resistance of the joint will not be completely eliminated.
