Abstract
Metallurgical powder compositions are provided that contain a metal powder that is associated with a polymeric material in admixture with a solid, particulate polyether lubricant. The incorporation of the polyether lubricant enhances the green strength properties of compacted parts made from the powder compositions, and generally reduces the ejection forces required to remove the compacted part from the die cavity.
