The invention discloses an aluminum alloy split-type I-type thrust rod, wherein the material of the thrust rod is aluminum alloy, and the preferred composition can be Al-Cu-based alloy, Al- Si-based alloys, Al-Mg-Si-based alloys, Al-Mg-Si- Cu-based alloy or Al-Mg-based alloys, and aluminum alloys in which trace alloying elements such as Sr, La, Ce, Y, Sc, Er, Nb, B, and Cr are added to the aluminum-based alloys. The aluminum alloy split-type I-type thrust rod sleeve is composed of a ball head and a ball hinge, two ends of the sleeve are respectively installed with a ball head, and the ball hinge is installed in a through hole of the ball head; The neck of the spherical head is a combination of an elliptical shape and an arc shape, which improves the bearing capacity. The aluminum alloy thrust rod sleeve and the ball head are prepared by a hot extrusion molding and/or a forging molding process. As that sleeve and the ball head are arrange by friction welding or friction stir welding, the thrust rod is obtained, and the weight reduction effect can reach 40 to 70 percent.
