Abstract: An aluminum component and a method for manufacturing the aluminum component has a forming step and a cutting step. Projections (f) extend in an axial direction and are continuously arranged in a circumferential direction. End portions of the projections (f) are cut along a processing line having a predetermined processing diameter (D) providing splines (S) of predetermined dimensions. Side surfaces (fa) are inclined to be tapered in a direction from a base end to a projecting end. A portion of each side surface (fa) adjacent to the projecting end is an inclined surface (fb) with an inclination angle less than an inclination angle of a portion of the side surface that is adjacent to the base end.
