The 2020 Automotive Aluminum Alloy Annual Development Report Is Officially Released


Aluminum alloy can be said to be the most influential material in automobile lightweighting, and it is also the first choice material to replace traditional steel for automobile manufacturing. In recent years, with the development of automotive aluminum alloy materials and application technology, the development of a series of high-performance new materials such as super strong aluminum alloys, superplastic aluminum alloys, high temperature resistant aluminum alloys, and aluminum foams has also continuously promoted the development of aluminum alloy materials in Application process on the car. At the same time, the development and maturity of technologies such as differential pressure casting, high vacuum high pressure casting, semi-solid molding, and thermoforming have also continuously opened up the application of aluminum alloys in automobiles. In addition, the rapid development of domestic new energy vehicles has greatly promoted the industrialization of domestic aluminum alloys in automobiles, and all-aluminum bodywork has been implemented in batches. For example, NIO ES8 (all-aluminum body model with sheet metal structure); Geely Englon TX and QIANTU K50 (all-aluminum body model with frame structure).


Based on this, the China Automaterial Website and the Autolightweight Online Research Team sorted out the aluminum alloy technology progress, the latest application cases, etc. through industry surveys, and aimed at application needs, bringing together a large number of application cases and statistical data. "The 2020 Automotive Aluminum Alloy Annual Development Report Is Officially Released" is officially released.
