Patent

CA 2669706

The invention relates to a method for the production of a cast component made of an aluminium diecasting alloy, in which the cast component is subjected to a heat treatment process after casting, wherein an aluminium diecasting alloy is used, by means of which the cast component has an elongation at break A5 of >= 10 % and a yield point R p0.2 of < 120 MPa, and wherein a single-step annealing process for stability is carried out at a temperature of 120-260 °C, after which the heat- treated cast component has a break at elongation A5 of >= 7 % and a yield point R p0.2 of >= 110 MPa. Furthermore, the invention relates to a cast component which is produced in accordance with a method of this type.
