This specification covers a silver-brazing flux in paste form.

This flux has been used typically for silver brazing nickel alloys, ferrous metal, including austenitic steels, and tungsten and chromium carbides, at temperatures in the range 1100 to 1800 \mDF (593 to 982 \mDC), but usage is not limited to such applications. Flux may also be used for critical applications involving long heating cycles for high temperature brazing, or for uneven heating cycles such as quick induction heating applications.
