Abstract
In one embodiment, a brazing sheet comprises: a core layer, a braze liner on the first side of the core layer; and a waterside liner on the second side of the core layer. The core layer is comprised of a 3xxx series aluminum alloy. The waterside liner is an aluminum alloy comprising: 7-20 wt % Zn; up to 0.25 wt % Si; up to 0.1 wt % Cu; up to 0.25 wt % Mn; up to 0.1 wt % Mg; and up to 0.1 wt % Cr. In some embodiments, the brazing sheet has a thickness of 60-180 microns. In some embodiments, the waterside liner comprises 1-15% of the thickness of the brazing sheet.
