69080181 - ESAB All-State Duzall General Purpose Soldering Flux - 4 oz

Industrial Grade General Purpose Soldering Flux

The ESAB All-State Duzall Flux (SKU: 69080181) is a premium chemical agent designed to facilitate the soft soldering of a wide variety of ferrous and non-ferrous metals. Formulated as a highly active liquid flux, Duzall is engineered to break down tenacious surface oxides that typically hinder the soldering process, ensuring superior wetting and capillary action. This 4 oz bottle provides a sufficient quantity for numerous maintenance and fabrication tasks, offering a reliable solution for joining dissimilar metals.

Technically, Duzall operates within an active temperature range of approximately 400°F to 800°F. This range is optimal for most soft soldering alloys, including tin-lead and lead-free compositions. The flux's chemical composition is aggressive enough to treat stainless steel, chrome, monel, copper, brass, cast iron, steel, and galvanized iron. It effectively lowers the surface tension of the molten solder, allowing it to flow deeply into joints and create hermetic, mechanically sound bonds. It is important to note that due to its chemical nature, this flux is not suitable for aluminum or magnesium applications, which require specialized flux formulations.

In industrial environments, the removal of flux residue is a critical step to ensure the longevity of the joint. The residues left by All-State Duzall are corrosive if left unchecked but are designed to be water-soluble. A simple post-solder wash with warm water is sufficient to neutralize and remove any remaining chemicals, preventing future corrosion. This feature makes it highly practical for MRO (Maintenance, Repair, and Operations) workflows where efficiency and durability are paramount. The product is packaged in a durable container that allows for safe storage and easy dispensing directly onto the workpiece.
