BRAZING SHEET AND FLUX COMPOSITION |
| 摘要 |
A brazing sheet includes a core material containing an aluminum alloy including magnesium, a bonding material laminated on at least one side of the core material, and a flux layer. The flux layer is laminated on one side of the bonding material and includes a flux composition. The flux composition includes [A] a flux component containing KAlF4, and [B] AlF3. A substance mass S1 (mol) of magnesium in the bonding material when heated at 585° C., a substance mass S2 (mol) of [A] the flux component containing KAlF4 in the flux layer and a substance mass S3 (mol) of [B] AlF3 satisfy the specific expression. |

1. A brazing sheet comprising:
a core material comprising an aluminum alloy comprising magnesium; a bonding material laminated on at least one side of the core material; and a flux layer laminated on one side of the bonding material and comprising a flux composition, wherein the flux composition comprises: [A] a flux component comprising KAlF4; and [B] AlF3, and a substance mass S1 (mol) of magnesium in the bonding material when heated at 585° C., a substance mass S2 (mol) of [A] the flux component comprising KAlF4 in the flux layer and a substance mass S3 (mol) of [B] AlF3 satisfy the following expression (1):
6S1/(42S2−18S1)≦S3/S2≦80S1/(42S2−18S1) (1). |
