Brazing Flux

"Brazing Flux, commonly referred to in the industry simply as flux, is an indispensable auxiliary chemical material in the brazing process. Its primary function is to break down and remove contamination and oxide films from the metal surface, allowing the molten liquid filler metal (brazing alloy) to flow smoothly, adhere firmly, and fill the joint clearances—ultimately bonding the two metal parts securely together.

NOCOLOK is a registered trademark owned by the global chemical giant Wacker Chemie (or Solvay, depending on the current corporate division), serving as a synonym and the pinnacle industry benchmark for non-corrosive aluminum brazing processes worldwide. In the manufacturing of aluminum heat exchangers—such as automotive air conditioning condensers, radiators, new energy vehicle battery cooling plates, and residential air conditioning evaporators—NOCOLOK brazing flux plays an absolutely dominant role.
