Production of cast components such as crank case/motor-blocks from aluminum-silicon die-casting alloy by low pressure/gravity permanent mold casting, comprises subjecting the component to hot-isostatic pressing, air cooling and storing

摘要

The method for the production of cast components such as crank case or motor-blocks from aluminum-silicon die-casting alloy by low pressure or gravity permanent mold casting, comprises subjecting the cast components to hot-isostatic pressing at 470-510[deg] C, an air cooling and a storing at 243-253[deg] C for 2-5 hours. The air cooling is carried out in still air. An independent claim is included for cast components such as crank case or motor-blocks from aluminum-silicon die-casting alloy.
