摘要

A process for the manufacture of a ferrous-based sintered article containing copper in the range from 12 to 26 weight% is described, the process including the steps of: making a powder mixture having a desired composition, at least a proportion of a total content of iron and copper being provided by an iron powder having copper indivisibly associated therewith for instance being pre-alloyed or diffusion bonded; compacting said powder mixture to form a green compact of an article to be produced and sintering said green compact.
