Title:
CLADDED ALUMINIUM-ALLOY MATERIAL AND PRODUCTION METHOD THEREFOR, AND HEAT EXCHANGER USING SAID CLADDED ALUMINIUM-ALLOY MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/104761
Kind Code:
A1
Abstract:
Provided are: a cladded aluminium-alloy material exhibiting high corrosion resistance and high mouldability, and a production method therefor; and a heat exchanger using said cladded aluminium-alloy material, and a production method therefor. This cladded aluminium-alloy material is provided with: an aluminium-alloy core material; an intermediate layer material used to clad one surface of the core material; and a brazing material used to clad the intermediate-layer-material surface which is not at the core material side. The core material, the intermediate layer material, and the brazing material are each provided with a prescribed alloy composition. The crystal grain size of the intermediate layer material before brazing heating is at least 60 µm. In a cross section of the core material in a rolling direction before brazing heating, when R1 (µm) represents the crystal grain size in a plate thickness direction, and R2 (µm) represents the crystal grain size in the rolling direction, R1/R2 is not more than 0.30.
