-13- ABSTRACT OF THE DISCLOSURE A method of making high density powdered metal compacts and also a method for making high density powder metal sintered products is disclosed. With respect to the compacts, iron powder of a coarse or fine configuration is mixed or coated with a low melting metal additive selected from the group consisting of tin, copper-tin, copper-lead, or lead in a percentage by weight of 2 5 of the admixture. The admixture is subjected simultaneously to both heat (at a temperature level such that the low-melting alloy is in a liquid phase) and pressure which is in the range of 10-30 tsi. Upon relief of heat and pressure, the agglomerated or compacted product will possess an increased density in excess of 80% and an improved hardness and strength level. With respect to a sintered product, the powder metal is selected to have a line particle size (average range of about 4-5 microns) and the powder is dry impact coated by ball milling with a low-melting additive such as tin, copper-tin, copper-lead or lead; the coated particles are warm briquetted and subjected to a sintering operation whereby the resulting product has a minimum density of 97% or more.
