FLUX BRAZING ALLOYS
Clad Aluminum Designed
for High-Integrity Brazed Assemblies
Lynch Metals supplies flux brazing alloys in clad aluminum sheet and coil form—engineered for high-performance applications that require strong bonds, thermal efficiency, and corrosion resistance. These materials are used across automotive, aerospace, HVAC, and industrial thermal systems for producing leak-tight, lightweight, and high-strength assemblies.
Whether you need 4045, 4343, or 4104 clad layers, we provide flux brazing materials cut to your exact spec—ready for fabrication or automated brazing.

Key Features
- Clad aluminum with controlled cladding thickness
- Ideal for controlled atmosphere brazing (CAB)
- Excellent bond strength and corrosion resistance
- Consistent flow and wetting behavior
- Available in bare or multi-clad formats
