Abstract: Automobile lightweight is the trend, and aluminum alloy replacing traditional steel has become an important technological approach for lightweight. Automobile belong to durable consumer goods, and the driving environment is complex and variable. In order to meet consumer needs, vehicle manufacturers need to study the quality management requirements of aluminum alloy replacement parts. This article takes the evaluation of the material characteristics of 6000 series aluminum alloy sheets commonly used in automotive panels as an example, and introduces the indicators and verification methods for evaluating aluminum alloy sheets from both quantitative and qualitative aspects, which can serve as a research reference for automotive manufacturers.
