摘要： A crankcase for a reciprocating piston engine, in particular of a motor vehicle, includes at least first one wall region that has a greater wall thickness than at least one second wall region of the crankcase that adjoins the first wall region. The crankcase is produced from an aluminum alloy and by at least mainly laminar die casting and is heat-treated completely or heat-treated completely and additionally locally or heat-treated only locally.
