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. Filler alloys BAlSi-6, -7 and -8 have magnesium introduced for this purpose. It is thought that thermal expansion of the aluminum base
Oct 07, 2013.When the magnesium vaporizes starting at around 1058 deg F (570 deg C), it acts as a etter for oxygen and water vapor, thus improving the purity of the brazing vacuum. Magnesium will also reduce the alumina oxide that exists on the surface of the aluminum to promote uniform accelerated wetting of the joint surfaces.

Apr 02, 2019.In vacuum aluminum brazing, magnesium is used as an additive to the filler metal or the base metal, and this serves two purposes. The heaters are typically mounted in a 360 octagonal arrangement or curved strips (Fig. 13) that fully surround the load to provide good temperature uniformity. Figure 13 | Curved graphite resistance heaters 1
In vacuum brazing the filler alloy contains 1.0-2.0% magnesium, which diffuses on the surface during the brazing cycle and the vaporizes at 600 degree due to low pressure of 105mbar. The Mg-vapour disrupts the oxide layer and thus enables the filler alloy to flow. aluminum brazing alloy,aluminum disc,transformer aluminium strip,aluminum
