Overview
Batch vacuum aluminum brazing
Batch VAB furnaces are single- or dual-chamber vacuum aluminum brazing systems designed for high-quality, fluxless brazing of aluminum components. They are available in two main configurations: suspended-load furnaces with dedicated transport mechanisms, and tray-loaded batch furnaces for aerospace and commercial heat-treating applications. The system uses magnesium activation within a high-vacuum environment to remove oxides and moisture, ensuring uniform wetting and clean, oxide-free joints. Batch VAB furnaces provide stable vacuum conditions, multi-zone heating control and flexible loading options for complex assemblies.
Applications
Where VAB Batch is used
