According to the invention, an outstanding punch riveting suitability is achieved if the die-cast component has a temperable aluminum alloy with the following alloying components: from 5.0 to 9.0 wt % silicon (Si), from 0.25 to 0.5 wt % magnesium (Mg), and residual aluminum as well as inevitable production-related impurities, containing at most 0.05 wt % of each and at most 0.15 wt % collectively, wherein the die-cast component has a yield strength (Rp0.2) of greater than 190 MPa and an elongation at break (A5) of greater than or equal to 7% and the uniform elongation (Ag) and necking elongation (Az) satisfy the condition Az?Ag/2.

Abstract: A temperable aluminum alloy, an aluminum sheet or strip made of such an aluminum alloy, a molded part, and a method for producing such a molded part have been disclosed. In order—despite the low hot tempering temperature and high deformability—to enable achievement of the required yield strengths Rp0.2, a temperable aluminum alloy is proposed, containing from 2.5 to 3.5 wt. % zinc (Zn), from 0.5 to 1.5 wt. % magnesium (Mg), from 0.2 to 0.8 wt. % silicon (Si), from 0.005 to 0.2 wt. % tin (Sn) and/or indium (In) and/or cadmium (Cd), and optionally from 0 to 0.35 wt. % copper (Cu), from 0 to 0.3 wt. % silver (Ag), from 0 to 0.25 wt. % iron (Fe), from 0 to 0.12 wt. % manganese (Mn), from 0 to 0.10 wt. % titanium (Ti), and residual aluminum as well as inevitable production-related impurities, wherein the content of magnesium (Mg) and silicon (Si) fulfills the order relation 0.4 wt . ? % ? ? Si - 0.15 < wt . ? % ? ? Mg < 0.7 wt . ? % ? ? Si - 0.2 .

Abstract: A method for producing an impeller of an exhaust gas turbocharger made of TiAl alloy by centrifugal casting, includes providing a TiAl alloy consisting of titanium, 43.7 at-% to 47.5 at-% aluminum, 1.9 at-% to 8.7 at-% niobium, 0.3 at-% to 0.6 at-% carbon, and at most 2.0 at-% others, heating a casting mold used for the centrifugal casting to a casting temperature of 500° C. to 800° C.; introducing the TiAl alloy into the heated casting mold; accelerating the casting mold about a rotation axis spaced apart from the casting mold with an angular acceleration to a rotational speed within an acceleration time period as soon as the TiAl has reached the casting temperature, wherein a rotary axis of the produced impeller is arranged perpendicular to the rotation axis during the centrifugal casting.
