Galaxy uses vacuum furnace brazing for aerospace and defense assemblies that require clean, flux-free joints and uniform heating. Brazing takes place inside a sealed furnace chamber with the air removed, so the assembly is heated without exposure to oxygen or other atmospheric contaminants.
Because the entire assembly is brought up to temperature slowly and evenly, vacuum brazing is well suited to complex designs with many joints that need to be brazed in the same furnace cycle.
Vacuum furnace brazing joins components by heating the full assembly at very low atmospheric pressure. With oxygen and other atmospheric gases removed from the chamber, the filler alloy can melt and flow into the joints without flux, and parts come out of the furnace clean, with no flux residue to remove.
The furnace follows a controlled thermal cycle, bringing the assembly up to brazing temperature uniformly and then cooling it under control. Even heating helps limit distortion and supports consistent joint formation across every joint in the assembly.
Vacuum furnace brazing can be a useful option for:
Joint design, materials, filler alloy, and thermal cycle all affect the result of a vacuum braze. Galaxy reviews those variables with your team before production begins, so the furnace process is established around the required metallurgical outcome.
