Abstract

A multilayered flux-cored silver brazing material, comprising an inner core layer, an intermediate layer attached to the surface of the inner core layer, and an outermost layer wrapped on the intermediate layer, the inner core layer being an alloy wire (1), the intermediate layer being a silver flux layer (2), the outermost layer being a silver-based brazing metal skin (3), and the melting point of the alloy wire being lower than that of the silver flux layer. Also provided is a production method for the multilayered flux-cored silver brazing material. In the multilayered flux-cored silver brazing material, the melting temperature of the core alloy wire is lower than that of the flux; in a brazing process, the alloy wire first melts and then adheres to the flux, so as to cause the flux to flow out into a brazing seam in advance, thereby improving the seam filling performance and flowability of the brazing material, and solving the problems of poor fluidity, difficulty in passing through the seam, and brazing material accumulation on the front brazing side during brazing using conventional flux-cored silver brazing materials, thus improving the brazing effect.
