Sintered shaped bodies are made of a pulverulent mixture of tin, copper and predominantly iron by sintering the mixture in which tin is present in an amount between 0.5 and 4.5%, copper is present in an amount of 0.3 to 7%, balance iron, and wherein the ratio of tin to copper is between 1 : 0.7 and 1 : 1.5. The formed sintered body is then cooled to for instance room temperature and thereafter subjected to a tempering treatment at a temperature between 750.degree. and 600.degree.C followed by cooling to room temperature. The cooling after the heat treatment and preferably also the cooling after sintering are effected at a slow rate at least within the range between 750.degree. and 300.degree.C, that is, at a rate not exceeding 15.degree.C per minute.
