<P>PROBLEM TO BE SOLVED: To provide a molding of a hypereutectic aluminum-silicon alloy rolled material, having a desired shape, and a method for manufacturing the molding of hypereutectic aluminum-silicon alloy rolled material. <P>SOLUTION: The molding of a hypereutectic aluminum-silicon alloy rolled material is obtained by performing deep drawing or bulging of a hypereutectic aluminum-silicon alloy rolled material including 13.0-30.0 mass% of silicon and less than 8.0 mass% (including 0 mass%) of magnesium and having an aluminum content of 50 mass% or more. The molding of a hypereutectic aluminum-silicon alloy rolled material contains a crystalized silicon having a size of 70 μm or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
