WIPO Patent Application WO/2015/162911

Kind Code:

A1

Abstract:

Provided are an aluminum cladding material having excellent corrosion resistance, a production method therefor, an aluminum cladding material for heat exchangers having excellent corrosion resistance, a production method therefor, an aluminum heat exchanger using said aluminum cladding material for heat exchangers, and a production method therefor. Said aluminum cladding material comprises an aluminum alloy core material and a sacrificial positive electrode material layer clad upon at least one surface thereof. The sacrificial positive electrode material layer comprises an aluminum alloy containing at least 0.10 mass% and less than 1.50 mass % Si and 0.10-2.00 mass% Mg. Present therein is 100-150,000/mm2 of Mg-Si crystallized products having a circle-equivalent diameter of 0.1-5.0 µm, 7/mm2 of same having a circle-equivalent diameter of more than 5.0 µm and no more than 10.0 µm.
