PROBLEM TO BE SOLVED: To provide an aluminum alloy die-casting component in which the reduction of production cost can be achieved, and which is produced at high strength and high quality even if a casting defect is generated. SOLUTION: Disclosed is an aluminum alloy die-casting component produced by a common die casting method using an aluminum alloy as the material. This component is produced in such a manner that Rockwell hardness is controlled to HRB≥50 in a state where thickness is controlled to≤5 mm. COPYRIGHT: (C)2009,JPO&INPIT
