Component, in particular for a vehicle, and method for producing such a component
A component includes a sub-region, where the component is produced at least in the sub-region by an additive manufacturing process. The sub-region is produced from an aluminum alloy which has 12% by weight to 40% by weight silicon, 0.3% by weight to 4% by weight copper, 0.2% by weight to 0.7% by weight magnesium, at most 1% by weight iron, at most 0.5% by weight zirconium, and a remainder which includes aluminum and further accompanying elements and/or production-related impurities that each have a mass fraction of at most 0.3 percent individually and that in total have a mass fraction of at most 1.5 percent.
1 . A component, comprising:
a sub-region, wherein the component is produced at least in the sub-region by an additive manufacturing process;
wherein the sub-region is produced from an aluminum alloy which comprises:
12% by weight to 40% by weight silicon;
0.3% by weight to 4% by weight copper;
0.2% by weight to 0.7% by weight magnesium;
at most 1% by weight iron;
at most 0.5% by weight zirconium; and
a remainder which comprises aluminum and further accompanying elements and/or production-related impurities that each have a mass fraction of at most 0.3 percent individually and that in total have a mass fraction of at most 1.5 percent,
wherein the component is part of an internal combustion engine, and
wherein at least the subregion of the component comprises a finer microstructure than cast alloys of the same chemical composition.
