Ipeco delivers high-integrity aluminium structures using salt bath dip brazing — a process we’ve refined in-house for over 50 years. This joining method is ideal for producing strong, lightweight, and complex assemblies where performance and precision are paramount.
What Is Salt Bath Dip Brazing?
Salt bath dip brazing is a highly controlled process for joining aluminium components by immersing assemblies into molten salt. This ensures uniform heating, minimal distortion, and creates continuous, leak-tight joints.
The method is particularly effective for pressurised, cooled or RF/EMI-shielded structures, delivering clear advantages over welding, casting and mechanical fastening.
Ideally suited to military-grade enclosures and components, from radar chassis and avionics housings to cooling plenums and heat exchangers, the process produces assemblies that are lightweight, robust and reliable.
Key Advantages
Lightweight yet robust – strength without excess weight
Structural flexibility – joins sections from 1mm to 50mm
Superior conductivity – outperform adhesives and fasteners
Large capacity – assemblies up to 30” × 45” × 34”
Design freedom – complex internal cavities and geometries

Backed by experience
Dip brazing has been a core part of Ipeco’s capability since the 1970s. From early use in aircraft crew-seat structures to today’s complex defence components, our salt bath brazing facility remains one of the most capable and comprehensive in Europe.
