Provided is a resin-coated aluminum alloy sheet characterized in that the sheet has a coating resin layer formed of a cured resin composition comprising an epoxy resin and a curing agent, the coating resin layer comprising a graphite particle with an amount of 5.0 to 25.0 parts by mass relative to a total of 100.0 parts by mass of the epoxy resin and the curing agent and a silica particle with an amount of 3.0 to 28.0 parts by mass relative to a total of 100.0 parts by mass of the epoxy resin and the curing agent, and a thickness of the coating resin layer being 2.0 to 25.0 μm. According to the present invention, it is possible to provide the resin-coated aluminum alloy sheet having both a good heat radiative property and a high moisture resistance.
An aluminum alloy disc blank for a magnetic disc made of an aluminum alloy containing Mg: 3.40 to 3.90 mass % with the balance being A1 and inevitable impurities, wherein a conductivity of the aluminum alloy disc blank is 36.0% IACS or higher.
