FLUX FOR BRAZING ALUMINUM MATERIALS

摘要

The present invention provides a flux for brazing aluminum-based materials, the flux being capable of brazing an A5052 alloy or the like containing 1.5 wt % or more of magnesium even when an Al—Si eutectic alloy (Si content: 7 to 12 wt %; A4343 alloy, A4047 alloy; melt starting temperature: about 577 to 615° C.) is used as a brazing material. Specifically, the present invention provides a flux for brazing aluminum-based materials, comprising, expressed in mol %, 20 mol %≦CsF≦49 mol %, 1 mol %≦LiF≦58 mol %, 19 mol %≦AlF3≦41 mol %, and 0 mol %
