Abstract
A method for casting an aluminum alloy includes: pouring molten metal of an aluminum alloy comprising 6.0 to 9.0 mass % of Si, 0.4 to 0.8 mass % of Mg, 0.25 to 1.0 mass % of Cu, 0.08 to 0.25 mass % of Fe, 0.6 mass % or less of Mn, 0.2 mass % or less of Ti, and 0.01 mass % or less of Sr, with the balance being Al and unavoidable impurities into a shot sleeve of a die casting machine; filling a mold cavity of a center-gate die with the molten metal at a gate speed of 1 msec or less so as to produce a laminar flow, and subjecting T5 heat treatment so as to obtain the aluminum alloy having a tensile strength of 240 MPa or more.
