Abstract

Aluminum sheet products having high strengths and favorable crashworthiness are disclosed. The aluminum alloys include Si, Mg and Mn in controlled amounts which provide high yield strengths while retaining formability and crash resistant properties. The sheet products undergo heat treatment and slow quenching. The sheet products are particularly suitable for use as auto body sheet products.
