Abstract

An iron base powder mixture capable of providing excellent fluidity at room temperature and in a warm state and reducing an extruding force in molding and having improved moldability; a method of production of this mixture; and a method of production of a high density molded article by using the mixture. The iron base powder mixture contains iron base powder, a lubricant and alloying powder, and at least one of the components is coated with at least one surface treating agent selected from the group consisting of organoalkoxysilanes, organosilazanes, titanate coupling agents and fluorocoupling agents. The iron base powder mixture is press-molded at a temperature higher than the lowest melting point but lower than the highest melting point of the lubricants contained in the mixture.
