The substitution of traditional steel with aluminum alloy is an effective approach of lightweight design of passenger car chassis structural parts, especially in high-end passenger car. This article introduces the development process of aluminum alloy sub-frame. The development practice shows that, with the application of aluminum alloy and extrusion casting technology, with the aid of rational design of structure and systemic development of technology, the strict requirements on strength and durability of chassis structural component can be satisfied, and the lightweight level of vehicle is improved.
