Vacuum Brazing Processes of Aluminum Foam
Rare Metal Materials and Engineering, 2013Abstract Butt joints of aluminum foam were made by three different brazing processes including brazing with multilayer filler metal in high vacuum of 10−3 (Pa) degree, brazing with multilayer filler metal in low vacuum of 1 (Pa) degree and brazing with monolayer filler metal in high vacuum of 10−3 (Pa) degree.

Zinc Distribution in Vacuum Brazed Alclad Brazing Sheet
SAE Technical Paper Series, 1978<div class="htmlview paragraph">Vacuum brazing technology is currently capable of producing aluminum automotive heat exchangers such as radiators and heater cores. The possible use of 7072 claddings on the surfaces exposed to the coolant to provide additional corrosion protection is of considerable interest.

Considerations on a new brazing concept for vacuum brazing of aluminium and copper
Welding in the World, 2020Mixed joints made of aluminium and copper are increasingly important in industrial applications. This type of mixed joint is of interest, e.g. when good electrical and thermal properties, as in power electronics cooling, are required. The joining requirements consist of the formation a metallurgical bond and planar joint between aluminium alloys and ...

SAE Technical Paper Series, 1972
<div class="htmlview paragraph">Fluxless vacuum brazing is now a commercially feasible process for joining a large variety of aluminum heat exchangers, particularly the common automotive and aircraft types. The advantages offered by this process include: improved quality of the brazed assemblies, lower production costs, elimination of air and ...

Vacuum brazing of mild steel using eutectic CuSil brazing alloy
Materials Today: Proceedings, 2021Abstract Need for joining similar and dissimilar materials with various thickness and geometry increasing rapidly, inferable from their bit of leeway of light-weighting in the automobile and aviation industries. Brazing is such method expanding quickly with the approach of reasonable high-temperature furnaces incorporated with high vacuum systems ...

Characterization of Vacuum Brazed Joints for Superconducting Cavities
Microchimica Acta, 2004Brazing is a process to join metallic and non-metallic materials, without any melting or plastic state of the base metals. The poor wettability of ceramic may be improved by the use of alloys containing an element capable of changing the chemistry of the ceramic surface (active braze).

A Mechanistic Study of Aluminum Vacuum Brazing
SAE Technical Paper Series, 1987<div class="htmlview paragraph">The vacuum brazing of aluminum is an established industrial process which relies on strict process and materials control for the successful joining of products such as heat exchangers. The operating procedures developed for vacuum brazing are largely empirical and the interaction between materials and processing on

TIG-plasma brazed vacuum joints
Vacuum, 1990Abstract The standard heating procedures for making a sealed joint are in practice not always convenient. In our work the plasma from TIG-welding apparatus was used for melting the braze. Very good vacuum tightness proved with helium leak-detectiion was obtained in such a way. Our contribution describes the problem, the different ways to solve it and
