Product Overview
Harris SSWF7 Stay-Silv White Brazing Flux is an all-purpose, low-temperature paste flux supplied in a 6.5-ounce jar with a brush cap. It is formulated for silver-brazing applications that use normal heating cycles and is designed to spread smoothly, provide even coverage, and protect compatible base metals as the assembly approaches brazing temperature. The attached brush cap supports controlled application at joints, fittings, and other localized work areas.
Stay-Silv White Flux is recommended for copper and copper alloys other than aluminum bronze, as well as steel, stainless steel, nickel alloys, and other ferrous base metals. It may be used with many high-silver brazing filler metals and with suitable phosphorus-copper-silver alloys, including copper-to-brass work. Harris specifies an active temperature range of 1,050°F to 1,600°F (565°C to 870°C). It is not recommended for aluminum, magnesium, or titanium. Flux residue should be removed after brazing according to the manufacturer’s guidance to reduce the possibility of corrosion. Read the current label and Safety Data Sheet before use, and follow appropriate ventilation, personal-protective-equipment, and hot-work procedures.
