Electric soldering iron aluminum and copper welding What the flux?
Replay:
Rosin, coupled with some fine iron filings. The procedure is this: aluminum welding parts coated with rosin, plus some iron filings, with large iron stained solder, repeated friction welding. When filings rosin under the protection of the surface of aluminum oxide film is removed, and the solder plating on the aluminum surface. In this case, it is possible to press the normal welding copper and aluminum welding together.
