Title:
ALUMINUM ALLOY CLADDING MATERIAL FOR HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2016/080433
Kind Code:
A1
Abstract:
Provided is an aluminum alloy cladding material for a heat exchanger, the material having superior brazing properties and external surface corrosion resistance so as to be suitable for use as a tube material or a tank or header material in an aluminum alloy heat exchanger manufactured by brazing. The present invention is characterized in that: one surface of a core material, which is composed of an aluminum alloy including 0.5-1.8% of Mn, limited to 0.05% or less of Cu, and comprising the remainder of A1 and unavoidable impurities, is cladded with a skin material 1 which is composed of an aluminum alloy including 3-10% of Si, 1-10% of Zn and the remainder of A1 and unavoidable impurities; and the other surface of the core material is cladded with a skin material 2 which is composed of an aluminum alloy including 3-13% of Si, limited to 0.05% or less of Cu, and comprising the remainder of A1 and unavoidable impurities, to thereby form a three-layer cladding material, wherein, when the amount of Si in the skin material 1 is X (%) and the amount of Si in the skin material 2 is Y (%), the value of (Y-X) is -1.5-9%, and the skin material 1 is used on the air side.
