Recommended for steel and copper alloys including most brasses. However, moderate ductility feature requires that dissimilar metal joints be in compression while cooling. Lower silver content limits joint design to close fit-ups.
Procedure
Thoroughly clean parts to be brazed. Joint clearance should not exceed .003". Apply All-State 110 or S-200 paste flux to joint area. Heat joint area rapidly with slightly carburizing flame until flux turns clear. Melt off enough 125 alloy to fill joint completely. Keep torch in constant motion so as not to overheat. Maximum brazing temperature is 1600°F. Allow to cool slowly; remove flux residue with hot water.
