Stay-Silv® White Powder Flux Brazing Flux HARRIS

Stay-Silv® White Powder Flux is a homogenous brazing flux developed to provide consistent coverage and dependable oxidation protection during brazing operations. The formulation includes boron to extend the active life of the flux, allowing it to remain effective during longer heating cycles.

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

The powder form allows flexible application methods, including mixing with water to form paste for easier application depending on operational requirements.
