Abstract: The exemplary embodiments relate to a multilayer aluminum alloy sheet material suitable for fabrication into coolant-conveying tubes, headers and the like used for heat exchangers, and to the tubes and headers, etc., fabricated from the sheet. The multi-layer metal sheet has a core layer of aluminum alloy having first and second sides. The first side has an interlayer made of a Zn-containing aluminum alloy positioned between a Zn-containing outer layer and the core layer. The alloy of the outer layer is more electronegative than the alloy of the interlayer. The alloy of the interlayer is preferably more electronegative than the alloy of the core layer. The first side clad in this way is the side intended for exposure to the coolant, and provides good resistance to corrosion and erosion.

Abstract: The present invention provides an aluminum alloy fin stock material with higher strength, and improved sag resistance for use in heat exchangers, such as automotive heat exchangers. The aluminum alloy fin stock material is produced from an aluminum alloy comprising about 0.8-1.4 wt % Si, 0.4-0.8 wt % Fe, 0.05-0.4 wt % Cu, 1.2-1.7 wt % Mn and 1.20-2.3 wt % Zn, with the remainder as Al. The aluminum alloy fin stock material is made by a process comprising direct chill casting the aluminum alloy into an ingot, preheating the ingot, hot rolling the preheated ingot, cold rolling the ingot and inter-annealing at a temperature of 275-400° C. After inter-annealing, the aluminum alloy fin stock material is a cold rolled in a final cold rolling step to achieve % cold work (% CW) of 20-35%.
