Title:
ALUMINUM ALLOY CLADDING MATERIAL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/007020
Kind Code:
A1
Abstract:
Provided is an aluminum alloy cladding material having an aluminum alloy core material, an intermediate layer material cladded to one surface of the core material, and a first filler metal cladded to a surface that is not on the core material side of the intermediate layer material, said aluminum alloy cladding material being characterized in that the core material, the intermediate layer material, and the first filler metal are formed from an aluminum alloy having a predetermined composition, the existence density of Al-Mn intermetallic compounds having a circle-equivalent diameter of 0.1 μm to 1.0 μm in the intermediate layer material before brazing heating is at least 1.0×105 compounds/mm2, and the existence density of Al-Mn intermetallic compounds having a circle-equivalent diameter of 0.1 μm to 1.0 μm in the intermediate layer material after brazing heating is at least 1.0×104 compounds/mm2. Further provided is a manufacturing method for the aluminum alloy cladding material.
