摘要

The structural element (1) has A-column (3) with two column elements. The former column element is formed as a lower column element (5) in sheet design and is made of aluminum, particularly high-or very high-strength aluminum or high or very high strength aluminum alloy. The latter column element is formed as an upper column element (7) from aluminum-composite cast. The latter column element has a cast-in insert that is made of steel, aluminum or aluminum alloy.
