1. An aluminum cast component being cast from an aluminum component casting alloy consisting of, in % by mass:
 
 
 Ce: 0.7-3.0%
 
 Si: 0.5-1.5%
 
 Fe: 0.1-1.2%
 
 Mg: 0.2-1.0%
 
optionally one or more elements taken from the group consisting of Zn and Sr, the content of the respective optional element being
Zn: ≤0.8%
Sr: ≤0.1%, and
the remainder being Al and unavoidable impurities, said unavoidable impurities including elements from the group consisting of Ti, Cr, Mn, and V, the content of said unavoidable impurities restricted in sum to less than 0.025%,
wherein the aluminum cast component in the as cast state (F-Temper) has an electrical conductivity of at least 42% IACS, a Brinell-hardness of at least 45 HB10/500, a yield strength (“YS”) of at least 80 MPa, and an ultimate tensile strength (“UTS”) of at least 150 MPa.
