Title:
ALUMINUM ALLOY BRAZING SHEET AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2015/001725
Kind Code:
A1
Abstract:
This aluminum alloy brazing sheet comprises: a core material comprising an aluminum alloy; an Al-Si brazing filler cladded to one surface of the core material; and a sacrificial anode material cladded to the other surface of the core material. The core material contains a predetermined amount of Si, Fe, Cu, and Mn, and furthermore a predetermined amount of one or more elements selected from Ti, Zr, Cr, and V; the sacrificial anode material contains a predetermined amount of Si, Fe, Mg, and Zn; there are no greater than 300 per mm of Al-Mg-Cu intermetallic compounds present at the interface between the core material and the sacrificial anode material in a cross section along the thickness direction and parallel to the lengthwise direction, and the structure of the core material and the sacrificial anode material is an unrecrystallized structure. The aluminum alloy brazing sheet has superior post-brazing strength and welding performance while being thin.
