Title:
ALUMINIUM ALLOY BRAZING SHEET HAVING HIGH STRENGTH, HIGH CORROSION RESISTANCE, AND HIGH MATERIAL ELONGATION
Document Type and Number:
WIPO Patent Application WO/2016/076263
Kind Code:
A1
Abstract:
The present invention comprises an aluminium alloy clad material obtained by cladding a sacrificial material on one surface of a core material and cladding an Al-Si or Al-Si-Zn brazing material on the other surface, wherein: the core material has a composition containing, by mass%, 1.3-2.0% Mn, 0.6-1.3% Si, 0.1-0.5% Fe, and 0.7-1.3% Cu, wherein the balance comprises Al and inevitable impurities; the sacrificial material has a composition containing, by mass%, more than 4.0% but at most 8.0% Zn, 0.7-2.0% Mn, 0.3-1.0% Si, 0.3-1.0% Fe, and 0.05-0.3% Ti, wherein the balance comprises Al and inevitable impurities; and with respect to the condition of the material, at least the crystal grain structure of the core material has a layered structure, the elongation of the material is 4% or more, and the tensile strength after brazing is 170 MPa or more.
