摘要： The invention relates to a recyclable aluminum foil. The foil is made of an alloy containing 0.2%-0.5% Si, 0.4%-0.8% Fe, 0.1%-0.3% Cu, and 0.05%-0.3% Mn by weight. with the balance aluminum and incidental impurities. The foil contains at least about 2% by weight of strengthening particulates and has at least about 0.1% by weight of the copper and/or manganese retained in solid solution. The invention also relates to a method of manufacturing a sheet of aluminum based on an alloy which involves continuously casting an alloy of the above composition to form a sheet of alloy, coiling said sheet of alloy, cold rolling the sheet of alloy, interannealing the alloy after a first pass of the cold rolling; and further cold rolling the alloy to a final desired gauge. The foil, which is suitable for household use, has improved strength due to a larger quantity of dispersoids fortified by elements in solid solution, and can be recycled with other alloy scrap.
摘要翻译：本发明涉及可回收的铝箔。箔由含有0.2％-0.5％Si，0.4％-0.6％Fe，0.1％-0.3％Cu和0.05％-0.3％Mn的合金制成。余量为铝和杂质。箔包含至少约2重量％的强化颗粒，并且具有保留在固溶体中的至少约0.1重量％的铜和/或锰。本发明还涉及一种制造基于合金的铝片的方法，该方法包括连续铸造上述组成的合金以形成合金片，卷绕所述合金片，冷轧合金片，将合金中间退火经过第一次冷轧; 并进一步将合金冷轧至最终所需的规格。适用于家庭用途的箔片由于固溶体中的元素强化而分散质量较大，因而具有改善的强度，并可与其他合金废料一起回收利用。

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.

摘要： High strength foil having dead fold foil characteristics is produced without the rolling and other production problems encountered with prior high strength foils by controlling manganese content, interannealing temperatures and, optionally, final annealing temperatures. The alloy contains 0.05 to 0.15 %, preferably 0.095 to 0.125%, manganese by weight. Cold worked sheet is interannealed at a temperature of about 200° C. to about 260° C., preferably 230° to 250 ° C., to produce substantially fully recrystallized sheet while maintaining most of the manganese in solid solution. The interannealed sheet is rolled to final gauge and finally annealed, preferably at a temperature of about 250° C. to about 325° C., more preferably about 260° C. to about 325° C., to produce dead fold aluminum foil with a yield strength of at least 89.6 MPa (13 ksi), and ultimate tensile strength of at least 103.4 MPa (15 ksi) and a Mullen rating of at least 89.6 kPa (13 psi) at a gauge of 0.0015 cm (0.0006 inch).

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.
