69080212 - All-State Brazaloy No. 53 General Purpose Brazing Flux 8 oz

Technical Overview of ESAB All-State Brazaloy No. 53 Flux

The ESAB All-State Brazaloy No. 53 Flux is a high-performance chemical agent formulated specifically for general-purpose brazing applications. Designed to facilitate the joining of a broad spectrum of metals, this flux is essential for achieving metallurgically sound bonds in maintenance, repair, and fabrication environments. It is engineered to function effectively across the typical temperature ranges required for brazing ferrous and non-ferrous alloys, including steel, cast iron, malleable iron, copper, brass, and bronze.

Chemically, the flux acts as a powerful deoxidizer. Upon heating, it liquefies and dissolves surface oxides that form on the base metal, creating a clean surface necessary for the brazing filler metal to wet and flow. This action significantly reduces the surface tension of the molten filler metal, promoting superior capillary action even in tight joint clearances. By forming a protective barrier over the heated metal, it prevents further oxidation from the surrounding atmosphere during the brazing cycle, ensuring porosity-free joints and consistent mechanical strength.

The product is supplied in an 8 oz container, typically in powder form, which can be used as-is by dipping the heated brazing rod into the jar, or mixed with water to form a paste for brush application. Its formulation is balanced to provide good visibility of the weld pool and easy post-braze cleaning. Residues left after the process are generally soluble in hot water, simplifying the finishing process. This flux is an integral component of the ESAB All-State line, known for quality solutions in specialty welding and joining.
