The automobile manufacturing industry is one of the fields in which the alloy material is used most. The alloy materials used in automobile production include Al-mg alloy materials, titanium alloy materials and other alloy materials. The use of new alloy materials instead of steel materials can effectively reduce the weight of cars and improve their quality. Many automobile manufacturers are constantly introducing new alloy materials. At present, automobile chassis has also begun to use various alloy materials.

We know that the role of the chassis is to carry the vehicle body, engine, interior and exterior decoration and other system weight modules, while supporting and accepting the power of the engine, so that the car can ensure normal driving. The chassis consists of four parts: drive train, driving system, steering system and brake system. If alloy materials are used in production, these properties need to be guaranteed as well as more stablity.

As consumers demand more and more performance for reliable and durable automotive products, the chassis system, which is a bearing component, is more secure and reliable.

The rapid development of the domestic new energy automobile and the increase of the weight of the motor battery also bring pressure for light weight. The reduce of unsprung weight will obviously increase the comfort and control stability of the automotives. However, the light weight, reliability and durability of the chassis are realized, and the new alloy material and the forming and manufacturing process matched with the new alloy material need to be continuously adopted. Therefore, the new technology of new alloy materials, such as aluminum, hydroforming, thermoforming, and composite materials, is constantly emerging.

The product design of chassis system of whole car factory, the supplier of key parts of chassis, the new material enterprises of chassis, research institutes and colleges and universities will focus on the technical trend of chassis system and the solutions of chassis lightweight. The development of new alloy material and new technology of chassis, the innovative scheme of modular chassis of new energy vehicle are researched and explored, and the technical development of chassis system and the key application technology of new alloy material and new technology are discussed together.
