FLUX FOR BRAZING ALUMINUM MATERIALS

FLUX FOR BRAZING ALUMINUM MATERIALS

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...

description 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, the flux comprising LiF, AlF 3 , and CsF, and the composition ratio of the three components being adjusted to within the range enclosed by four lines: line C connecting (30, 0, 70) and (30, 70, 0), line (1) connecting (31, 33.5, 35.5) and (51.5, 22.5, 26), line (2) connecting (32.5, 28.5, 39) and (49, 21.5, 29.5), and line (3) connecting (57.5, 42.5, 0) and (57.5, 0, 42.5), excluding the points on line C, in the triangular coordinates indicating LiF mol%, AlF 3 mol%, and CsF mol%.
