摘要： 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.

摘要： A method of imparting a non-stick coating to a surface of an aluminum foil sheet, and the resulting foil sheet. The method involves coating at least part (preferably at least 40%) of an area of a surface of a metal sheet article (preferably an aluminum foil sheet) with a substantially solvent-free silicone oil at an average coating application rate in a range of 1.5 to 10 mg/ft2 of the coated surface area. The coated sheet article is then preferably coiled. The coated sheet article is then heated in the presence of air or oxygen at a temperature of 250° C. or higher for a period of time of at least 10 minutes. The treated surface is both non-stick and food-friendly.
