Title
(EN) BRAZED STRUCTURE
(FR) STRUCTURE BRASÉE
(JA) ろう付け接合構造体
Abstract
(EN)
This brazed structure includes a brazing sheet that has been brazed and that comprises: a core material comprising an aluminum alloy which contains 0.3-1.0 mass%, excluding 0.3 mass%, Si, 0.6-2.0 mass%, excluding 0.6 mass%, Mn, 0.3-1.0 mass%, excluding 0.3 mass%, Cu, and 0.15-0.5 mass%, excluding 0.15 mass%, Mg, with the remainder comprising Al and unavoidable impurities, and has an average crystal grain diameter of 50 μm or larger and in which an Mg-Si intermetallic compound and an Al-Mg-Si-Cu intermetallic compound account for 40% or less of the grain boundaries; and, clad to the core material, a brazing material comprising an Al-Si alloy.
