Abstract: Seven property demands for aluminum alloy auto sheet are systematically summarized and proposed,which could make the project of research and developing about aluminum alloy auto sheet have a obvious target.Typical chemical composition,mechanical properties and formability of aluminum alloy auto sheets are introduced.The main factors effected the properties are demonstrated.The pre-treatment technology and its importance to guarantee the performance of the auto sheet are deeply discussed.The important research contents about the sheet are pointed out and the application is described.Reducing cost and price of the sheet and deeply developing application study are important work for expending application of aluminum alloy sheets.
