An aluminum alloy sheet is manufactured by preparing a slab having a thickness of 5 to 15 mm with a continuous casting machine by a continuous casting process using molten alloy containing 0.40% to 0.65% of Mg, 0.50% to 0.75% of Si, 0.05% to 0.20% of Cr, and 0.10% to 0.40% of Fe, a remainder being Al; winding the slab into a coil; cold-rolling the slab into a sheet; subjecting the sheet to solution heat treatment in such a manner that the sheet is heated to a temperature of 530&#xb0; C. to 560&#xb0; C. at a heating rate of 10&#xb0; C./sec or more and then maintained at the temperature for five seconds or more; quenching the sheet with water; coiling up the sheet; maintaining the sheet at a temperature of 60&#xb0; C. to 110&#xb0; C. for 3 to 12 hours; and then cooling the sheet to room temperature.

Aluminum alloy sheet and method for manufacturing the same

An aluminum alloy sheet having excellent press formability and stress corrosion cracking resistance, comprises 3.3 to 3.6 percent by weight of Mg and 0.1 to 0.2 percent by weight of Mn, furthermore, 0.05 to 0.3 percent by weight of Fe and 0.05 to 0.15 percent by weight of Si, and the remainder comprises Al and incidental impurities, wherein the sizes of intermetallic compounds is 5 &#x3bc;m or less, the recrystallized grain size is 15 &#x3bc;m or less in the region at a depth of 10 to 30 &#x3bc;m below the sheet surface, and the surface roughness is Ra 0.2 to 0.7 &#x3bc;m.

A continuous belt casting apparatus is provided with a casting cavity, and at least one flexible metal belt having an elongated casting surface passing through and at least partially defining the casting cavity. A motor is provided for rotating the metal belt in the longitudinal direction of the casting surface whereby the casting surface passes through the casting cavity in the longitudinal direction. A molten metal supply device delivers molten metal continuously to the casting cavity, so that molten metal supplied to the casting cavity is solidified and removed as a continuous strip ingot from the casting cavity by rotation of the belt. The casting surface is provided with a plurality of grooves oriented in substantially the same direction. The invention also relates to a casting belt for such an apparatus and a method of casting using the apparatus.
