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 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： A process for forming hollow microspheres containing carbon or a polymer which is a carbon precursor. The process comprises forming a solution in a liquid solvent of a polymer having the following properties (a) a molecular weight of at least 10,000 and a long chain structure; (b) an ability to be coagulated by or precipitated from the solution by a non-solvent for the polymer; (c) an ability to form a continuous stretchable film when coagulated or precipitated from solution; (d) a chemical structure which is infusible or capable of being rendered infusible, and (e) a high carbon yield of at least 30% by weight upon being carbonized in a non-reactive atmosphere. An insoluble particulate blowing agent is incorporated into the solution and the solution is then divided into droplets and the droplets are introduced into a liquid bath containing a suitable non-solvent for the polymer. The non-solvent causes the polymer to precipitate or coagulate rapidly and simultaneously the blowing agent is decomposed to generate a gas within the droplets so that hollow microspheres are formed. The microspheres are then optionally subjected to carbonization in a non-reactive atmosphere at high temperature to convert the polymer to carbon. Uniformly-sized relatively large hollow microspheres can be produced by this process.

摘要： A method of treating a surface of a metal foil or sheet to make the surface wettable. The method comprises obtaining a metal foil or sheet having an oil-coated surface to be treated, applying a solution of phosphoric acid in a polar, non-aqueous, water-free solvent evenly to the surface at a rate of application in a range of at least 10 mg/ft2, the phosphoric acid being contained in the solution at a concentration such that the phosphoric acid contacts the surface in an amount of 0.5 to 2.0 mg/ft2; and removing the solvent by either drying the surface or heating the foil or sheet at an elevated temperature above ambient to evaporate the oil from the surface to be treated with the proviso that the elevated temperature does not fall in the range between 130 to 240° C. The resulting foil has a wettable surface and can be used, for example, for coating with a layer of another material (e.g. polymer or adhesive) and achieve high peel strength.
