vacuum brazing aluminum foil

Aluminum vacuum brazing technology introduction

The vacuum brazing of Al and aluminum alloy does not use flux, but under vacuum conditions (3-5.0×10-3 Pa), with the help of M g, which has a higher vapor pressure and a greater affinity for O2 than Al The metal activator removes the film, and Mg is added as an alloying element to the aluminum-silicon solder.

Vacuum Brazing - an overview | ScienceDirect Topics

A number of materials are suitable for Fe 3 Al alloy vacuum brazing, including pure aluminum foil, Cu-based alloys, Ag-based alloys and Ni-based alloys. 5 When pure aluminum foil is selected as the interlayer for Fe 3 Al alloy vacuum brazing, the diffusion reaction area occurs in the joint, and the hard, brittle Fe 2 Al 5 phase will also form in this area. Diffusion treatment at high temperatures for a long …
