Abstract (en)

[origin: WO2021105229A1] The invention relates to a method for producing a die casting part and a die casting part produced with said method. According to the invention, an excellent punch-riveting suitability is achieved when the die casting part has a curable aluminium alloy with the following alloy constituents: 5.0 to 9.0 wt.-% silicon (Si), 0.25 to 0.5 wt.-% magnesium (Mg) and as the remainder aluminium and unavoidable impurities caused by production each with max. 0.05 wt.-% and in total at most 0.15 wt.-%, wherein the die casting part has a yield point (Rp0.2) of greater than 190 MPa and an elongation at break (A5) of greater than or equal to 7 %, and uniform strain (Ag) and necking strain (Az) meet the condition Az ≥ Ag/2.
