Stay-Silv® White Flux Brazing Flux HARRIS

Stay-Silv® White Flux is a homogenous paste brazing flux developed to provide smooth application, even coverage, and dependable oxidation protection during brazing operations. The addition of boron extends the active life of the flux, allowing it to remain effective through longer heating cycles.

This makes it suitable for induction brazing operations where intense localized heating occurs, as well as for heavier components requiring extended heating time. The flux supports proper filler metal flow while protecting base materials from oxidation, helping ensure strong and clean brazed joints.

Stay-Silv® White Flux is recommended for brazing copper and copper alloys except aluminum bronze, along with steel and other ferrous base metals. It is also commonly used for brazing stainless steel, nickel alloys, and tungsten carbide components.
