摘要： Extruded tubes for heat exchangers have improved corrosion resistance when used alone and when part of a brazed heat exchanger assembly with compatible finstock. The tubes are formed from a first aluminum alloy comprising 0.4 to 1.1% by weight manganese, up to 0.01% by weight copper, up to 0.05% by weight zinc, up to 0.2% by weight iron, up to 0.2% by weight silicon, up to 0.01% by weight nickel, up to 0.05% by weight titanium and the balance aluminum and incidental impurities. The fins are formed from a second aluminum alloy containing 0.9 to 1.5% by weight manganese or an alloy of the AA3003 type, this second aluminum alloy further containing at least 0.5% by weight zinc.

摘要： A process of heat treating a sheet article made of a 6000 series aluminum alloy to achieve good 'paint-bake response' that is substantially unaffected by natural aging. The process comprises heating the alloy sheet article at a solutionizing temperature followed by cooling the alloy sheet article. The cooling involves the following steps: (1) cooling from said solutionizing temperature to a temperature in the range of 150 - 250 °C at a rate greater than or equal to about 4 °C per second; (2) further cooling the alloy to a temperature in the range of ambient to 100 °C at a rate of 20 to 30 °C (preferably about 25 °C) per minute; and (3) further cooling the alloy sheet article having a temperature of 55 °C or more after step (2) to ambient temperature at a rate of less than 2 °C per hour. Alloy sheet articles suitable for use in the fabrication of automobile skin part can be produced in this way.

摘要： The invention provides an aluminum alloy material consisting essentially of, by weight percent, 1 % to 1.8 % Cu, 0.8 % to 1.9 % Mg, 0.2 % to 0.6 % Si, 0.5 % to 0.4 % Fe, 0.05 % to 0.30 % Mn, with the balance aluminum with normal impurities. The alloy forms two precipitation phases during heat treatment and age hardening: a beta phase of Mg2Si and an S' phase of Al2CuMg. The alloy has improved formability without significant sacrifice of strength, and is particularly suited to be formed into automobile sheet metal parts such as hood lids, trunks lids, and fenders.

摘要： A process of producing a shaped article suitable for use as an automotive body panel intended for finishing by painting and, if necessary, baking. The process comprises obtaining a sheet article made of an aluminum alloy of the 2000 or 6000 series in a T4 or T4P temper and that exhibits an increase in hardness after painting and optionally baking, shaping the sheet article by forming to produce an intermediate shaped article, and subjecting the intermediate shaped article to a thermal spiking treatment prior to painting and optionally baking. The thermal spiking treatment involves heating the intermediate shaped article from ambient temperature to a temperature in a range of 150 to 300 DEG C with or without holding at that temperature for a period of time to enhance the increase in hardness.

摘要： L'invention concerne un matériau en alliage d'aluminium se composant essentiellement de 1 % à 1,8 % en poids de Cu, de 0,8 % à 1,9 % en poids de Mg, de 0,2 % à 0,6 % en poids de Si, de 0,5 % à 0,4 % de Fe, de 0,05 % à 0,30 % en poids de Mn, le reste consistant en de l'aluminium avec des impuretés normales. L'alliage forme deux phases de précipitation lors du traitement thermique et du vieillissement : une phase bêta de Mg2Si et une phase S' de Al2CuMg. Cet alliage possède de meilleures caractéristiques de façonnage sans diminuer de façon significative la résistance, et s'applique notamment à la fabrication de pièces en tôle de carrosseries automobiles, telles que les capots, les coffres, et les pare-chocs.
