Formability of Aluminum Alloy Sheets and Recent Forming Technologies

摘要

Aluminum alloy sheets are applied to various kinds of products by press forming. In recent years, environmental problems are grown up and aluminum alloy sheets for autobody panel are attracting the attention to reduce the weight of automobile for fuel saving and reducing CO_2 in exhaust gas. In this report, firstly, the formability of typical aluminum alloy sheets is reviewed according to the types of forming. Then aluminum alloy sheets for autobody panel are explained in the history of alloy development, the characteristics of alloys and the formability. Finally, superplastic forming and incremental forming are described as the examples of recent forming technologies.
