Beschreibung
Zusammenfassung:	A particulate composite lubricant for powder metallurgy comprises: first discrete particles comprising at least about 90 wt% of a fatty primary monoamide wax, being substantially free of fatty bisamide wax, and being at least partially coated with metal oxide nanoparticles and second metal-stearate free discrete particles comprising a fatty bisamide wax. A particulate composite lubricant for powder metallurgy can comprise: a Montan acid ester wax and at least one fatty amide wax comprising at least one of a fatty monoamide wax and a fatty bisamide wax.
