Zusammenfassung:	A powder metal alloy composition is used in the production of a sintered powder metal insert for casting into an aluminum casting. The powder metal alloy composition includes an iron powder metal base, copper such that the copper is 3.5 weight percent or more of the powder metal alloy composition, and carbon in an amount of 0.1 to 1.0 weight percent of the powder metal alloy composition. Upon compacting and sintering the powder metal alloy composition to form the sintered powder metal insert, the sintered powder metal insert has a copper gradient that provides a higher concentration of copperon the surface of the sintered powder metal insert than in a center of the grains of the sintered powder metal insert. The higher concentration of copper at the surface of the insert enables a strongmetallurgical bond to be formed with the aluminum casting during casting. 粉末金属合金组合物用于生产用于铸造入铝铸件中的烧结粉末金属嵌件。粉末金属合金组合物包含铁粉末金属基底、铜和碳，以使得铜占粉末金属合金组合物的3.5重量％或更高，并且碳含量占粉末金属合金组合物的0.1至1.0重量％。在将粉末金属合金组合物压实并烧结以形成烧结粉末金属嵌件后，该烧结粉末金属嵌件具有铜梯度，所
