Abstract
Provided is a production method of an aluminum alloy forging for an automobile suspension having a disturbance affectable surface with not excessively notch-sensitive. The production method includes, as heat treatment processes, a solution heat treatment process, a quenching process, and an artificial age hardening process. The quenching process is performed by bringing a lower surface of the aluminum forging to be disposed on a ground side when assembled to the automobile into contact with water before an upper surface of the aluminum forging opposite to the lower surface is brought into contact with the water.
