Aluminum alloy cladding material for heat exchanger

Aluminum alloy cladding material for heat exchanger

An aluminum alloy clad material includes a core material, one side being clad with cladding material 1, the other side being clad with cladding material 2, the core material including an aluminum alloy that includes 0.5 to 1.8% of Mn, and limited to 0.05% or less of Cu, with the balance being Al and...

Zusammenfassung:An aluminum alloy clad material includes a core material, one side being clad with cladding material 1, the other side being clad with cladding material 2, the core material including an aluminum alloy that includes 0.5 to 1.8% of Mn, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, the cladding material 1 including an aluminum alloy that includes 3 to 10% of Si, and 1 to 10% of Zn, with the balance being Al and unavoidable impurities, and the cladding material 2 including an aluminum alloy that includes 3 to 13% of Si, and limited to 0.05% or less of Cu, with the balance being Al and unavoidable impurities, wherein the Si content X (%) in the cladding material 1 and the Si content Y (%) in the cladding material 2 satisfy the value (Y−X) is −1.5 to 9%.
