The Beginner's Guide to Vacuum Aluminum Brazing (VAB) By Signature Vacuum Systems, Inc. on July 6, 2018. / Vacuum Brazing. 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.
Vacuum Brazing Process. Selection of parts material. The workpiece to be brazed is a battery cooler. The parts are divided into main board, side board and pressing block. The main part is the main board, as shown in the figure. The alloy material of the brazing layer of vacuum brazing contains 1%-2% of Mg, and adding Bi element can improve the.
Vacuum brazing furnace for aluminium alloy. The chemical activity of high aluminum, easy oxidation, pressure over 6 * 10-3 Pa, in the heating process, parent materials and the filler metal is oxidized to grey, filler metal can not be wet base material. Only when the pressure is less than 5 * 10 – 3 Pa, and slow heating at 500 DEG C, 30min.
