Vacuum Aluminum Brazing Furnaces. Commonly, VAB furnaces are single-chamber batch type and are usually loaded horizontally but can be vertical loading type. Horizontal furnaces tend to be simpler in design (one loading/unloading door), less expensive, and easier to maintain. The VAB cycle is typically relatively short due to the pumping and heating characteristics of the furnace, excellent ...

03.11.2008 Most base metals typically brazed in vacuum furnaces have a natural oxide “coating” that can inhibit the flow of brazing filler metals. Conversely, alloys containing appreciable amounts of reactive elements such as aluminum and titanium tend to form oxides at high temperatures which impede the flow of the brazing filler metal. Many of the nickel-base superalloys fall into this category and ...
