The Harris Stay-Silv® White Brazing Flux is a premium-grade, all-purpose paste flux engineered for the rigorous demands of industrial silver brazing. Formulated with a proprietary blend of boric acid and fluoride compounds, this flux is designed to activate within a temperature range of 1050°F to 1600°F (566°C - 871°C). This specific thermal window makes it an optimal choice for the majority of silver brazing applications where normal heat cycles are utilized. The flux serves a critical metallurgical function by dissolving surface oxides and preventing further oxidation during the heating process, thereby facilitating the wetting and capillary action of the filler metal.
Compliant with AWS A5.31 Classification FB3-A, as well as AMS 3410 and Federal Specification O-F-499 Type B, Stay-Silv® White ensures reliability and consistency in code-critical environments. It is chemically compatible with a broad spectrum of base metals, including steel, stainless steel, copper, brass, bronze, and nickel alloys. However, it is specifically contraindicated for aluminum, magnesium, and titanium due to chemical incompatibility. The paste consistency allows for precise application, adhering well to vertical and overhead surfaces without running, ensuring that the joint area remains protected throughout the pre-heat and brazing phases.
In manufacturing and MRO (Maintenance, Repair, and Operations) settings, the quality of the flux directly correlates to the integrity of the brazed joint. Harris Stay-Silv® White promotes superior flow characteristics of silver brazing alloys, reducing the likelihood of voids or weak bonds. Post-braze, the flux residue can typically be removed, often with hot water or mechanical abrasion, leaving a clean, finished joint. Packaged in a durable 1 lb jar, this product offers a shelf life of two years, making it a staple consumable for professional fabrication shops requiring consistent, high-quality brazing results.
