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.
