摘要： The present invention relates to a lightweight part, particularly a vehicle body part, which includes sheet steel and light metal. In order to improve the manufacturability as well as the strength and rigidity properties, the sheet steel (6 through 8) is implemented as thin-walled, particularly has a thickness of less than 2 mm, and has at least one free area which is provided locally with a cast or sintered reinforcement structure (15) made of light metal.
