69080209 - All-State Brazaloy No. 31 General Purpose Brazing Flux Paste - 8 oz Jar

Technical Overview of All-State Brazaloy No. 31 Flux

The All-State Brazaloy No. 31 Flux is a premium general-purpose brazing flux formulated to meet the rigorous demands of industrial joining applications. Manufactured by ESAB under the All-State brand, this flux is engineered to facilitate the brazing of a wide variety of base metals, including steel, malleable iron, copper, brass, and bronze. It is supplied in a convenient 8 oz jar, providing sufficient quantity for extensive repair or fabrication tasks.

Technically, Brazaloy No. 31 operates within an active temperature range of approximately 1100°F to 1600°F (593°C to 871°C). This window makes it highly compatible with standard low-fuming bronze (LFB), nickel silver, and other common brazing filler metals. The flux composition is designed to become active before the filler metal melts, effectively dissolving surface oxides and preventing further oxidation of the base metal during the heating cycle. Its superior wetting characteristics ensure that the molten filler metal flows smoothly via capillary action into the joint, creating a sound, leak-proof bond with high mechanical strength.

The paste consistency of the flux allows for precise application to the joint area prior to heating, adhering well to vertical and overhead surfaces without running off prematurely. Post-braze residues are water-soluble and can typically be removed with hot water and mechanical agitation, simplifying the finishing process. This flux is an essential chemical consumable for maintenance, repair, and operations (MRO) environments where dissimilar metal joining or general steel brazing is required.
