Abstract
An iron-based powder mixture for powder metallurgy essentially consists of a melted mixture, as a binder, which includes about 0.1% to about 1.0% by weight of a powder of at least one organic compound selected from stearic acid, oleic acid amide, and stearic acid amide, and about 0.1% to about 1.0% by weight of a powder of stearic acid bisamide; and the balance which is an iron-based powder, to the surface of which adhered about 0.1% to about 3.0% by weight of an alloying powder and/or a powder for improving machinability. Disclosed also is a method of producing the mixture.
