Oct 29, 2010 Regarding a): Brazing of aluminum to stainless steel works both with NOCOLOK Flux + Al-Si filler alloy and with NOCOLOK Sil Flux. After the flux melts and the oxides are removed, there is a reaction between Al and Fe, forming a thin intermetallic layer of FeAl3. This layer forms the metallurgical bond between the Fe and Al components.
Aluminum brazing is a popular metal-joining technique that has several advantages over other forms of welding. Brazing is a form of torchwork that involves joining two pieces of metal with a nonferrous flux using gas that is heated to roughly eight hundred degrees Fahrenheit.
12Mar 19, 2010 Brazing aluminium to copper is common in the refrigeration industry where copper tubes are brazed to aluminium roll-bond panels or tubes. To join aluminium and copper using brazing technology and standard NOCOLOK Flux, flame brazing would be applicable (as well as using a low-melting flux with a low-melting filler metal). It is very similar to brazing aluminium to aluminium, but
Use an aluminum brazing alloy like Aluxcor 4047 to join the aluminum to the wetted steel; Youll probably find much better results with this two-stage method than with a single stage brazing process. For the single stage brazes, the braze itself is actually pretty soft and you wont get
8Torch brazing uses of flux always, which is a chemically aggressive combination of chlorides and fluorides that melts at a temp just below the filler metal. Torch brazing of very thin or very fine structures is really difficult, because of the inability to evenly heat the parts; Dip brazing aluminum is performed in a molten salt bath containing the flux.
Aluminum may be furnace brazed in air using flux. It is also possible to oven braze aluminum in a vacuum furnace without flux. Successfully vacuum brazing aluminum without flux requires a good vacuum (10-5 torr). The presence of magnesium, either in the base metal or the filler, seems to aid the process by acting as a getter for oxygen.

Aluminum brazing in a vacuum furnace is considered fluxless brazing because flux is not used to remove oxides. Vacuum pumps evacuate the furnace, thereby reducing the PPM oxygen level in the brazing chamber thus inhibiting oxide formation. Magnesium is used as a getter in vacuum aluminum brazing to enhance the purity of the braze environment ...
