摘要： An aluminum alloy sheet for a magnetic disk, a method for manufacturing same, and a magnetic disk using same. The aluminum alloy sheet is made of an aluminum alloy comprising 0.10 to 3.00 mass % of Fe, 0.003 to 1.000 mass % of Cu, and 0.005 to 1.000 mass % of Zn, with a balance of Al and unavoidable impurities, wherein a value obtained by dividing a difference in an area ratio (%) of second phase particles between a region (A) and a region (B) by an average value of area ratios (%) of second phase particles in the regions (A) and (B) is 0.05 or less, the region (A) being a region from a sheet thickness center plane to a front surface of the sheet, and the region (B) being a region from the sheet thickness center plane to a rear surface of the plate.

摘要： This invention provides an aluminum alloy material capable of being thermally bonded in a single layer without using a bonding agent, such as a brazing or welding filler metal. This invention also provides a bonding method for the aluminum alloy material, and an aluminum bonded body using the aluminum alloy material. The aluminum alloy material is made of an aluminum alloy containing Si: 1.0 to 5.0 mass % and Fe: 0.01 to 2.0 mass % with the balance Al and inevitable impurities. The aluminum alloy material contains 10 to 1×104 pieces/μm3 of Al-based intermetallic compounds having equivalent circle diameters of 0.01 to 0.5 μm and 200 pieces/mm2 or less of Si-based intermetallic compounds having equivalent circle diameters of 5.0 to 10 μm.
