High-Integrity Joining for Complex, Lightweight Assemblies
BTX Precision offers advanced aluminum vacuum brazing solutions for critical components that demand structural strength, leak-tight performance, and flawless surface integrity.

Flux-Free Brazing for High-Integrity Aluminum Assemblies
At BTX Precision, our aluminum vacuum brazing capabilities are built to support lightweight, high-strength assemblies where performance, cleanliness, and structural integrity are non-negotiable. From thermal control systems to aerospace and defense subassemblies, we deliver flux-free, contamination-free joints with unmatched consistency — all within tightly controlled, high-vacuum environments engineered for repeatability and precision.
High-Integrity Brazing for Demanding Designs
Vacuum brazing allows us to join aluminum components without flux, ensuring clean joints, no trapped contaminants, and exceptional mechanical properties. This process is ideal for complex, multi-part geometries and assemblies that require both thermal performance and structural integrity.
Key advantages include:
-
Flux-free brazing for clean, oxidation-free joints
-
Uniform heat distribution and tight temperature control
-
Exceptional dimensional stability during and after brazing
-
Strong, leak-tight joints ideal for pressure and fluid systems
-
Repeatable performance for high-volume production or critical one-offs
