Abstract
Flowability-improving particles containing 50 to 100% by mass of carbon black are adhered to surfaces of iron powder through a binder to provide an iron-based powder for powder metallurgy which has excellent flowability and which is capable of uniformly filling a thin-walled cavity, compaction with high ejection force, and maintaining sufficient strength of a sintered body in subsequent sintering.
