The definition of brazing is to join two or more pieces of metal by means of flowing a filler metal between the joint interfaces at a temperature below the melting point of the base metal but above 840°F....

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 ...

Vacuum brazing, and brazing in general, is an often-overlooked but highly essential process in metal joining. Its close cousins, soldering and welding, can at times overshadow this highly useful and effective joining process. Though it is often used in large-scale applications like automotive and ...
