Name: Solvay NOCOLOK Zn FLUX
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Solvay NOCOLOK Zn FLUX

Zinc-modified variant of the proven NOCOLOK® flux chemistry, enabling reliable brazing of aluminum-to-zinc-coated (e.g., galvanized) steel components.
Halide-free formulation ensures excellent corrosion resistance and eliminates post-braze cleaning requirements in most applications.
Low-melting, self-limiting activation enables uniform, controlled wetting without excessive base metal erosion or intermetallic formation.
Compatible with standard Nocolok® application methods including slurry spraying, dip coating, and powder preform placement.
Designed for vacuum and controlled-atmosphere furnace brazing, delivering consistent joint integrity and reproducible process windows.

Typical Applications Of Solvay NOCOLOK Zn FLUX

Aluminum heat exchangers with zinc-coated steel headers (e.g., automotive HVAC modules).
Brazed aluminum-to-galvanized steel assemblies in thermal management systems for electric vehicles.
Hybrid cooling plates integrating aluminum cooling channels with zinc-coated structural steel frames.
Aerospace cabin air distribution components requiring lightweight aluminum/steel dissimilar metal joints.
