Vacuum Aluminum Brazing (VAB)

What Is Vacuum Aluminum Brazing (VAB)?

Vacuum aluminum brazing represents a specialized joining methodology engineered specifically for aluminum materials. As a fluxless, atmosphere-controlled brazing technique, this process ensures an exceptionally clean and precisely regulated thermal cycle.

This process is highly favored in thermal management industries for manufacturing intricate assemblies like plate heat exchangers and custom liquid cooling plates because it minimizes thermal distortion and guarantees clean, oxidation-free finishes.

Advantages of Vacuum Aluminum Brazing

• Does not require the use of corrosive fluxes unlike dip or torch brazing
• The controlled atmosphere produces reliable leak-tight joints
• Utilizes magnesium, minimizing aluminum oxide presence
• Can be used with intricate brazing designs
• Multiple quantities can be brazed during a single cycle
